Introduction: The Importance of Transactions in Databases In the world of database management systems (DBMS), transactions are the fundamental units of work that ensure data is manipulated in a reliable and consistent manner. A transaction is a sequence of operations—such as reading, writing, updating, or deleting data—that must be completed as a whole. If any part of the transaction fails, the entire operation must be undone to prevent partial updates that could leave the database in an inconsistent state. This process of undoing a transaction is known as a rollback. But why do transactions get rolled back, especially when multiple operations "clash" or conflict with one another? And how does a database system decide when and how to roll back a transaction? These questions lie at the he…  ( 12 min )

The World's Largest Hackathon started with a single prompt—and ended up reshaping the way I think about building. I didn’t go in expecting life-changing revelations. I went in expecting a fun challenge, a few late nights, and maybe a cool demo by the end. But what I got was a deeper connection to the why behind my work. My project didn’t launch with a bang. It didn’t go viral or catch investor attention. But what it did do was remind me that finishing something is a win in itself. Throughout the hackathon, I learned to: Ship fast, and polish later Turn vague ideas into usable tools with Bolt.new Design for simplicity, not complexity Using Bolt.new as my foundation taught me a lot about building smart—not hard. I explored: Prompt engineering for logic flows and interfaces Rapid prototyping with AI as a partner Structuring apps with modular, testable components I got better at thinking like a builder who respects both time and user attention. That’s a lesson I’m carrying forward. The hackathon might be over, but the app is far from done. I’m not continuing development or slowly shaping it into something more polished and ready for real-world use. I'm using it as a stepping stone into something bigger because now i have learnt how to build and not just to build for building but to build with purpose. And I’m planning future builds with the same lean, idea-first approach I practiced here. Small, useful, and real. This hackathon taught me that momentum matters more than medals. That building fast is a skill. That the act of creating something out of nothing still feels like magic, every time. And that sometimes, showing up, building something honest, and hitting "Submit" is the real win. See you at the next hack. ✌️  ( 4 min )

Hey there, Linux enthusiasts! 👋 Ever felt lost in the labyrinth of rpm, yum, and dnf commands? Wondered what makes them tick, or why we even have different tools for what seems like the same job? You're in for a treat! This post will demystify Linux package management, taking you on a journey from the foundational RPM to the advanced capabilities of DNF. Get ready to level up your Linux game! 🎮 Think of RPM as the bedrock of package management on Red Hat-based systems (like Fedora, CentOS, RHEL, openSUSE). It's a low-level tool that deals directly with .rpm files. Foundation: It's the core format for packaging, distributing, installing, and managing software.

I found the following question on StackOverflow: How do I get my image to appear on my webpage? —StackOverflow I improved the question into: how do I make images appear on localhost? I do that because I was having that problem, and I could not explain the issue. Also, if that person asks the question in the context of an online website, the problem will be very easy to solve. This article answers both scenarios. In a computer, developers can activate localhost anywhere within their file system. They can start their localhost from the Desktop folder if they are on Windows. We use the following file structure for the working directory: my-project/ ├─ images/ │  ├─ panda.png ├─ index.html As an example, I can activate a localhost with the following steps: I start a localhost from Desktop.

How I’m architecting and building a scalable, multi-tenant document processing system. We've all been there—drowning in documents scattered across emails, cloud drives, and local folders. Important information buried in PDFs, critical insights lost in meeting notes, and that one crucial document that you know exists but can't find when you need it most. After experiencing this pain point repeatedly in my development work, I decided to build NeuroStash: an open-source knowledge management system designed to ingest, process, and intelligently extract information from document which can be self-hosted. But this isn't just another file storage solution—it's a production-ready system built with scalability, security, and developer experience in mind.

This is a submission for Frontend Challenge: Office Edition sponsored by Axero, Holistic Webdev: Office Space I built a dynamic and engaging intranet homepage using only HTML, CSS, and JavaScript. The interface includes a personalized welcome message that greets users based on the time of day and their name, stored locally for a consistent experience across visits. It also features a floating virtual assistant icon that opens a helpful panel with quick-access internal resources. This design provides a user-friendly, modern look while remaining lightweight and accessible without a backend. It contains again news sections, archives highlights and other thing. Link of deployment : https://frabjous-twilight-eeed40.netlify.app/ Github link with MIT License : https://github.com/Judakp/FrontendChallenge-Axero.git I started by designing a clean layout, prioritizing user engagement and usability. The first component I implemented was the dynamic welcome message, using JavaScript to greet users according to the current hour and storing their name via localStorage. This makes the experience feel personal and consistent. Next, I added a virtual assistant bubble that stays fixed at the bottom corner. When clicked, it reveals a compact panel with helpful internal links like accessing documents, contacting HR, or checking the schedule. I used smooth hover effects and light shadows to make the interface visually appealing and intuitive. I finally created news sections , archives highlights and other thing.  ( 3 min )

When I signed up for the World's Largest Hackathon, I expected late nights, last-minute bugs, and a rollercoaster of caffeine-fueled coding sessions. What I didn’t expect was how human the experience would be. Although I built my project entirely solo, I never felt like I was working in a vacuum. The global energy during the hackathon was contagious. Whether it was reading through other builders’ updates or catching the AMA replays, there was always something to keep me motivated. Even in moments of silence, I felt connected. I had the chance to attend a local satellite event in Lagos—a gaming room turned hacker den for the weekend. The LED lights were glowing, keyboards clicking, and the vibe? Somewhere between “startup garage” and “LAN party.” We passed around cookies and ice cream, exchanged stories, and celebrated small wins like fixing stubborn bugs or finally nailing down an AI prompt. It was low-key, but that shared atmosphere of creation made it unforgettable. Bolt Team – for making app development feel like alchemy. The way I could scaffold a backend and logic with simple prompts changed everything. Eric Simons & Greg Isenberg’s AMA – raw, honest, and incredibly grounding. A reminder that every big build started as a rough sketch. Discord Community – while I didn’t reach out for help directly, just seeing the energy, memes, builds, and support from fellow builders gave me the push I needed. Yes, I shipped something I’m proud of. But the real win wasn’t the product—it was the experience. The community, the chance encounters, and the late-night moments when I remembered why I love to build in the first place. If you’re thinking about joining the next hackathon: do it. Even solo, you won’t be alone. The code may be yours, but the momentum is shared. Huge thanks to everyone who made this journey unforgettable. Catch you in the next build. 🚀  ( 4 min )

SSL certificate strategy must be greatly considered when managing multiple subdomains for your website, as a business owner or a web deliver. Would it be better to buy an individual SSL certificate for single subdomain or simply procure a timesaving wildcard SSL certificate? Let us discuss about that cost-benefit functionality and the actual practicalities. A wildcard SSL certificate uses an asterisk (*) as a placeholder to secure a primary domain and all its first-level subdomains with a single certificate. For example, a certificate for *.example.com would automatically secure: blog.example.com shop.example.com api.example.com admin.example.com And any future subdomains you create Cost Analysis: Wildcard vs Individual Certificates The financial argument for wildcard SSL becomes compelli…  ( 4 min )

Introduction Git is not just a tool — it’s the lifeline of modern software development. Yet, many junior developers underestimate its power. If you don’t master Git early, you’ll soon find yourself drowning in broken branches, lost commits, and unsolvable merge conflicts. This guide covers the absolute must-know Git commands that every junior developer should engrain into their muscle memory. 1. git init What it does: Initializes a new Git repository. If you’re starting a new project, run: git init Without this, Git won’t track your project. Forget this step, and you’re just coding in the void. 2. git clone What it does: Clones a repository from a remote source. git clone When you join a team or contribute to an open-source project, this is how you grab the code. 3. git …  ( 4 min )

If you've been keeping an eye on modern web development trends, you've probably heard a lot of chatter about edge functions, edge computing, or “running your code at the edge.” No, it’s not some new punk band. It’s the next step in how we build fast, scalable applications, and it’s not just hype. So, what are edge functions? Why should you care? And how do they fit into modern stacks? Traditionally, when someone makes a request to your app, it hits a centralized server, maybe in Virginia, maybe in Frankfurt, maybe in some giant AWS data center somewhere. Edge functions are like mini serverless functions that run at those edge locations.

Yesterday, I asked GPT-4 to help me write a work email to a colleague. The response was technically perfect: clean grammar, polished structure, polite tone. But something felt off. It lacked the subtle understanding of our working relationship—the accumulated history, unspoken dynamics, and tone adjustments I’ve learned over time. It felt sterile. Here’s the fundamental problem: Current LLMs operate in isolation. Each conversation exists in a vacuum. They don’t remember yesterday’s context, adapt to our evolving needs, or grow with us over time. This isn’t a technical limitation — it’s an architectural decision. And it’s the wrong one. Human intelligence builds on context. You don’t reintroduce yourself to a friend every time you meet. Context-aware AI should work the same way. Traditional…  ( 5 min )

Let’s get this out of the way first: Git is confusing. No one picks up Git and immediately feels like a wizard. If you’ve ever stared at your terminal wondering what the heck detached HEAD means, you're not alone. Most tools do one job and do it simply. Git, on the other hand, is like a Swiss Army knife duct-taped to another Swiss Army knife. It tracks versions, coordinates collaboration, manages history, branches reality... and expects you to understand how all those parts fit together. Git makes a lot more sense once you understand how it actually works under the hood. Think of Git like a fancy key-value store. Every commit is just a snapshot of your code at a moment in time, and Git stores them as objects. Those objects are linked by hashes, not filenames. That’s why it doesn’t really c…  ( 4 min )

In the Linux world, 'Ricing', refers to the process of customizing your machine, and create a custom environment for yourself. The term 'rice' originates from the old internet slang which meant 'to make it look nice' and is now majorly used for customizing a desktop environment. The Ricing Culture, began soon after minimalist window managers like i3, or bspwm started to emerge in the early Linux days, providing users with a way to customize their entire desktop stack. Early on, this trend of customizing your desktop started to pickup and people started sharing configurations and screenshots with each other on early social platforms. Linux is the holy grail for ricing. Linux is like a modular puzzle, it is built up of small pieces that are replaceable and customizable as per the users choic…  ( 10 min )

Imagine handing the keys to your house, or even your entire neighborhood, to a global team of maintenance workers.

As a developer and content creator, I constantly write—whether it’s documentation, blog posts, email sequences, or even meta descriptions. And one thing I find myself checking more often than I expected? Word and character count. Sure, Google Docs does it. Word does it.

Microservices are supposed to be independent, autonomous, and scalable. But in reality, they often end up tightly coupled—relying on synchronous API calls, complex orchestration, and fragile dependencies. In this post, we’ll explore how to break microservice dependencies using a powerful pattern known as Event-Carried State Transfer (ECST)—or as I like to call it, Self-Contained Events. It’s a simple yet impactful idea: put all the necessary data in the event. Many microservice systems fall into a trap: they rely heavily on synchronous API calls between services to share data. This creates tight coupling, reduces resilience, and introduces latency.This API dependencies hurt reliability and scalability. Let’s say a customer places an order.

A Virtual Machine (VM) is a software-based computer that runs an operating system (OS) and applications, just like a physical computer. The key difference is that a VM is hosted on a physical server and managed through a virtualization layer called a hypervisor. In simple term, A virtual machine is a computer inside a computer. To manage the virtual machine, With the network settings updated to support segmenting the Linux virtual machine, you’re ready to manage the virtual machine itself. The first thing the Azure admin asks you to complete is moving the virtual machine to the new subnet you created in when updating the virtual network. Then secondly to vertically scale the virtual machine. Next is to attach data disks to the virtual machine and finally configure automatic shutdown on a v…  ( 4 min )

Let's be honest: effective web design for the hospitality industry has evolved far beyond just being a pretty online brochure. Think of your website as your most valuable employee—a powerful, 24/7 digital front desk that drives direct bookings, nurtures guest loyalty, and offers the very first taste of your unique experience. Picture your website as the grand entrance to your hotel, resort, or restaurant. It's your digital doorman, concierge, and brand ambassador, all rolled into one, working around the clock to welcome potential guests. For most people, this is the very first impression they'll have of you, and it sets the entire tone for their experience long before they even think about packing a bag. Today's hospitality websites are less about being a static information hub and more ab…  ( 18 min )

A couple of weeks ago, I started hearing more and more about something called Model Context Protocol (MCP). Actually, the first thing I saw was a TikTok by ChicaPython, and from that I kind of understood that MCP was like an API… but for communicating with LLMs (Large Language Models) 🤯. Then I started googling and found the official documentation, with several readings on the architecture of the protocol. From there, with some examples and tutorials using Claude, I jumped into the practical side. And here’s what makes it powerful: MCP is a standard protocol, declared in November 2024 (so yeah, pretty recent). And being a standard means it’s here to stay. From now on, this is how we communicate with LLMs, not just to consume services like when we used the Gemini API to create an agent. We…  ( 6 min )

A few days ago, while working on a bug at work, I noticed something odd: after I fixed the bug, the default client name value in a dropdown component took almost 2 to 3 seconds to appear after the page loaded. That kind of lag is probably unacceptable to users, so I know I had to dig deeper. Turns out, it was a performance issue. We always hear advice like “don’t optimize prematurely” or “only solve performance problems when they exist.” Well, this was the first time I actually ran into one myself — and I think the debugging process is worth documenting.

Title: Nurturing Compassion: A Journey from Self-Care to Altruism Introduction Compassion is a powerful emotional response that connects us to others. It is a genuine desire for their well-being and a willingness to alleviate suffering.

Does AI Hold the Key to Cybersecurity's Future? Here’s a wild stat to get us started: by the time you finish this paragraph, a new cyberattack has likely just launched somewhere in the world. Yep, that’s how fast and furious threats are coming at us these days. And honestly, it's starting to feel like traditional cybersecurity methods are playing an exhausting game of digital whack-a-mole—patching here, scanning there, reacting everywhere.

TL;DR: Two pointers is a powerful pattern for solving problems in sorted arrays. It’s faster than brute force and unlocks elegant solutions for many common interview questions. If you’ve ever seen a Leetcode solution that says “use two pointers” and thought: “Yeah sure... but why does that work?” You’re not alone. Two pointer problems look simple — but they feel like magic when you're new. So let’s break it down the way I wish someone had explained it to me: like we're pair programming side by side. Two pointers is a pattern where you use two indices (or “pointers”) to traverse an array — either from both ends or from the same direction — to solve a problem more efficiently than brute force. It’s mostly used when: The array is sorted You’re looking for relationships between elements (like…  ( 5 min )

In Azure, these types of unstructured non-relational data are referred to as blob (binary large objects). Company growth will probably translate to more site visits. Therefore, it is essential that the website content remains highly available, loads quickly, and supports features like version control and easy recovery. In this guided exercise from Microsoft, we will create and configure an Azure Storage account specifically for hosting this public content. We will make it high available, and the contents open for public read access. We will set up a blob container, practice uploading and testing fi…  ( 5 min )

In April 2022 I made a review of Haskell libraries for JSON Schema. The outcome of my research was that there weren't really any good libraries for dealing with JSON Schema from within Haskell. That was a surprising disappointment, because Haskell often has very good libraries (although they may be hard to use). The reason is that the JSON Schema specification itself isn't very well-made. I eventually gave up using any of them. Today Albert Krewinkel wrote me and told me that you can actually use AutoDoCodec to both generate and validate JSON schemas. The Haskell package autodocodec was announced in Haskell Weekly #291 in November 2021 by Tom Syd Kerckhove. I knew this library, but had never made the connection that it'd serve all my JSON schema needs. Since my original blog post felt like…  ( 6 min )

Most note-taking apps claim to be "encrypted" but still have a dirty secret: they can read all your data. When we built Typelets, we decided to do things differently - using true zero-knowledge encryption where even we can't decrypt your notes. Here's exactly how we did it using just the Web Crypto API. When apps like Notion say they're encrypted, they usually mean: ✅ HTTPS encryption in transit ✅ Database encryption at rest ❌ They still hold the keys to decrypt everything We wanted to build a notes app where privacy wasn't just a marketing claim - it was mathematically guaranteed.

How To: Delete Old Git Commits and Clear Sensitive Files from History Everyone works with GenAI apps (like ChatGPT, Gemini and Claude) and often forgets to delete the secret while pushing the code to Git/GitHub/BitBucket etc. Accidentally committing sensitive information (like passwords, API keys, or certificates) to a Git repository is a common mistake. Removing these sensitive files from your repository's history is critical to protect your project and users. This guide provides step-by-step instructions for three common approaches to erase old commits and clear unwanted files, with a recommendation for the most robust solution. GitHub has added the feature by NOT allowing the files to get pushed - but the user also has an option to force push with secret - which poses the security th…  ( 5 min )

Originally posted as a LinkedIn discovery that I just had to share with the dev community. The Discovery That Made Me Break My "No Social Media Posts" Rule I'll be honest,I don't usually write LinkedIn posts or blogs. But sometimes you stumble across something so useful that you feel obligated to share it with fellow developers and AI enthusiasts. LMArena (lmarena.ai), and it completely changed how I approach AI model testing and comparison. What Exactly Is LMArena? You submit a prompt Two AI models respond (you don't know which models they are) You vote for the better response The results feed into a public leaderboard based on real user preferences But here's the kicker,while you're participating in this research, you get free access to premium AI models that normally cost serious mone…  ( 5 min )

🚖 What Is a Ride Hailing System? A ride hailing service (like Uber or Lyft) is a platform that connects passengers with drivers through an app or website. Instead of waving for a cab on the street, you can request a ride with a few taps on your phone. Behind the scenes, this simple experience is powered by a complex distributed system involving real-time location tracking, matching algorithms, payments, notifications, and much more. Goal of This Article To explain, in simple terms, how to design the core components of a ride hailing service, focusing on the most important of system design concepts that make up the real-world solution. Core Components of the System Let's start with a high-level overview of the major pieces involved in such a system: User App (Passenger) Driver App Ba…  ( 6 min )

When developing, you may have heard terms like linear space O(n) and constant space O(1), or seen them completing coding challenges; but what do they actually mean? These terms describe the space requirements of an algorithm and how those requirements grow as the input size increases. They're part of what's known as Big O notation, a mathematical way to describe algorithmic efficiency — both in terms of time and space. This post focuses on space complexity. Space complexity refers to the amount of memory an algorithm needs to run, including: Input space: Memory used to store the input itself. Auxiliary space: Extra memory used during processing (e.g., temporary variables, stacks, arrays, etc.). In Big O notation, we usually refer to the auxiliary space, since input space is often cons…  ( 5 min )

Hey folks, Maybe it helps someone out there who’s still in the trenches. ⸻ Just start building — even if it sucks Seriously. I kept waiting until I “understood everything” before starting a project. That was a trap. ⸻ Get good at Googling Nobody remembers everything. The real skill is knowing what to search and how to phrase it. ⸻ Keep a “dump” file I always have a random file open (mine’s called junk.js) where I test stuff, break code, or just experiment. It’s like a no-pressure sandbox — no rules, no cleanup, just play. ⸻ Console.logs are fine. But learn the debugger Took me way too long to realize breakpoints and watch values are actually easy and save you so much time. Especially when stuff gets messy in loops or async code. ⸻ If you can’t explain it, you probably don’t get it Try explaining a concept out loud — to yourself or someone else. If you stumble, that’s a clue to revisit it. Writing blog posts or rubber-ducking really helps here. ⸻ It’s okay to delete code Sometimes when I’m stuck, the fastest fix is just… deleting the thing and starting over. I used to be scared of that, but it usually ends up cleaner the second time. ⸻ You don’t need to know everything There’s so much pressure to learn every new framework or language. Truth is, you can go very far by just going deep in one stack. Don’t burn out trying to chase every trend. ⸻ That’s it for now. Not groundbreaking, just honest stuff that helped me personally. If you’ve got a tip that saved you a ton of time or helped things finally click — I’d love to hear it. Drop it in the comments 🙌  ( 4 min )

General Introduction What is Reactive Programming? Wikipedia: Reactive Programming Reactive programming is a declarative programming paradigm focused on data streams and the propagation of change. It allows working with both static (e.g. arrays) and dynamic (e.g. event emitters) data flows, automatically handling updates via the Observer pattern. In essence, reactive programming is about data flow, asynchronous communication, and automatic propagation of changes. In Spring, the key difference between traditional Spring MVC and WebFlux is synchronous vs asynchronous processing. Instead of blocking to wait for a response, reactive code allows you to invoke a method and keep doing other work while waiting. Spring uses Project Reactor internally, which implements the Reactive Str…  ( 5 min )

I know I can get things done, no matter the challenge. But how do I do it effectively? That question has been on my mind for a while now. It's no longer about proving my capability to accomplish something, what's been driving me lately is a more subtle (and deeper) unease: the desire to do better! Capability Isn't the Hurdle If you work in tech, you've probably gone through the phase of learning new tools, frameworks, languages, and methodologies.

Remote team collaboration is no longer just a trend. It’s how modern teams get things done. But working from different locations can bring its own set of challenges, especially when communication, engagement, and accountability start to slip. What is Remote Collaboration? Remote collaboration is the process of working together toward shared goals while being physically apart. It relies on digital tools, such as video conferencing, shared documents, messaging apps, and virtual polling, to facilitate effective communication and keep projects on track.

While working with Git branches like develop and main, it's common to frequently merge changes. But did you know that doing so with regular merges can break a linear commit history? Here's what I learned today 👇 If you keep merging from develop to main using regular git merge, Git will create merge commits, leading to a non-linear (branched) commit history. This can make git log harder to read, especially in large projects. To ensure a clean, straight commit history on main, use one of these strategies: Rebase Before Merge git checkout develop git rebase main # Replay develop commits on top of main git checkout main git merge --ff-only develop # Fast-forward only ✅ This avoids merge commits and keeps the history linear. Use Squash Merging (Optional) If you want to combine all develop changes into a single commit before merging: git checkout main git merge --squash develop git commit 🎯 Useful for condensing work into one clean commit. Use Fast-Forward Merges Only Prevent accidental merge commits: git merge --ff-only develop 🔁 Repeat this pattern consistently to keep main clean and linear — great for production branches and readable history.

🚀 Modern Intranet Dashboard UI Built for the Axero Frontend Challenge Hadil Ben Abdallah ・ Jul 25 #devchallenge #frontendchallenge #css #javascript  ( 2 min )

This is a submission for Frontend Challenge: Office Edition sponsored by Axero, Holistic Webdev: Office Space I built a sleek Office Intranet Dashboard inspired by modern workspace needs. It includes announcement boards, employee directory, project status cards, and a meeting room booking UI. I used React + Vite, Lucide icons, and full responsive CSS to simulate a real office experience. Live App 👉 https://balamanikandanb191.github.io/-DEV-Frontend-Challenge/ GitHub Repo 👉 https://github.com/balamanikandanb191/-DEV-Frontend-Challenge This challenge helped me think like a real UI/UX designer for workplace tools. I planned the layout like an intranet dashboard you'd see in a tech company — with components like Announcements, Tasks, and Team Members. I used Framer Motion for smooth transitions and made the design completely mobile-responsive. Proud moment? I created a dynamic card grid system from scratch. I learned how important consistent UI is when building dashboards and how little details (icons, shadows, alignment) matter.

Introduction Launching a successful token presale is not just about having a great product or tokenomics—it’s also about building momentum, trust, and community engagement. One of the most effective ways to achieve this is by leveraging a revenue sharing model as part of your presale marketing strategy. This approach incentivizes community members, influencers, and promoters to actively participate in and promote your presale, creating a win-win scenario for all parties involved. A revenue sharing model in the context of a token presale is a system where a portion of the funds raised (or tokens sold) is distributed as rewards to promoters or referrers who help bring in new investors. This model transforms your community into an active marketing force, aligning their interests with the su…  ( 6 min )

There's been a flood of demos lately showing off how MCP servers can write WhatsApp messages or book plane tickets. Most of that feels like novelty, not utility. As a technical founder building Sliplane, a Docker hosting platform, I live in my terminal, and I care about things that help me ship, support customers, and write content fast. Quick refresher: MCP (Model Context Protocol) is Anthropic's open protocol that lets AI assistants like Claude connect to external tools and data sources. Think of MCP servers as bridges that give Claude access to APIs, databases, or services. Instead of copy-pasting information back and forth, Claude can directly interact with your tools to get work done. Here are four MCP servers I actually use every day to get real work done. No gimmicks. Just productiv…  ( 5 min )

Who Built It? How Proof of Attribution Gives Credit Where It’s Due In traditional software development or AI research, it’s easy to overlook one crucial question: Who actually built this? A dataset might be compiled by hundreds of people. A model could be fine-tuned over months by a team of engineers. Content might be pulled from the web, cleaned, annotated, and prepped by unseen hands. Yet, when the product goes live a chatbot, a new algorithm, a predictive tool credit is often centralized. The work of contributors gets buried under logos and branding. This is where Proof of Attribution (PoA) steps in a system designed to answer that very question: who contributed what, and how can we make sure they get recognized (and even rewarded)? Before diving into Web3, let’s look at ho…  ( 5 min )

Have you ever wished that you could learn a new language just by browsing the web? Well I know I have. About a year ago I decided that I wanted to learn Russian. Learning a new language is a slow process, so being able to spend time constantly working towards this goal is critical. However once the novelty of embarking on a new hobby wore off I found it harder and harder to engage and enjoy what I was reading, children stories just aren't that entertaining. This lead to me thinking, I wish I could engage with Russian the same way I do English every day. And this is where I decided to create Lingo Journey, a Chrome extension designed to help people learn a new language. If Language learning is all about immersion, then what better way to achieve this than surfing the web entirely in your n…  ( 4 min )

Wave provides a feature called inline assembly, and today we’re going to use it to directly call the BIOS. The int 0x10 interrupt is one of the most basic video output functions in real mode. By putting 0x0E into the AH register and the character you want to output into the AL register, then calling int 0x10, the BIOS will display the character on the screen. Using this method, we’ll print "Hi!", then perform a line break with CR (0x0D) and LF (0x0A), and finally print "OK". Currently, the Wave compiler can only be built on Linux, and by default it only generates executable binaries. It does not directly create a .img disk image like a bootloader would. However, when Wave compiles, it generates a /target folder that contains both an LLVM IR file (.ll) and a Linux binary. Since we want to c…  ( 5 min )

🧭 Day 2: Kicking off Auth Service – Exploring Keycloak vs. Duende IdentityServer In our journey to build a robust, secure, and scalable e-commerce platform (SmartKart 🛒) using .NET Core and Microservices, we are now diving into the Authentication and Authorization layer. Why Start With AuthService? 🔍 What is Keycloak (in simple words)? Keycloak is an open-source identity and access management tool. Think of it as a central place where: Users register and log in 🔑 Roles and permissions are managed 🛡️ Tokens (JWT) are issued for secure API access 🧾 And the best part? It already has all the features built-in — you don’t have to code login pages, password management, token handling, etc., yourself! ✅ Why We Chose Keycloak Over Other Options ASP.NET Identity + JWT (custom) Duende IdentityServer (formerly IdentityServer4) Keycloak Here's why I picked Keycloak: ✔️ 1. Fully Open Source ✔️ 2. Feature-Rich, Out of the Box ✔️ 3. Centralized User Management Add/edit users Assign roles Configure clients/apps ✔️ 4. Standards-Based Protocols ✔️ 5. Easy to Integrate with .NET Core JWT Bearer Authentication OpenID Connect client libraries ✔️ 6. Scalable & Cloud-Friendly 📌 Summary Comparison Table : Feature Keycloak ✅ Duende IdentityServer ❌ Open Source (free to use) ✔️ Yes ❌ No (requires paid license) Admin UI for users/roles ✔️ Built-in ❌ Needs custom development Login/Register/Forgot UI ✔️ Provided ❌ Build yourself Protocol Support (OAuth2/OIDC) ✔️ Yes ✔️ Yes Easy .NET Core Integration ✔️ Yes (via JWT/OIDC) ✔️ Native Multi-tenant support ✔️ Realms ❌ Manual effort  ( 3 min )

Background I am a developer. I love coding. But lately I started to be interested in this so called "Vibe coding". You know, on LinkedIn I see people claiming that they can do a complete application in hours, put them to market and don't need to hire developers. Now that I did some some experiments doing "vibe coding" I noticed that yes, it helps a lot, it makes some things faster, you don't have to do a lot of the big stuff, just focus on the solution and in the parts where you really have to think. My first experiment was doing an Android app called "Card Umen". My experience with Kotlin is almost zero (I made something for a hackaton in the past but forgot almost all), so I worked with chatgpt, claude and gemini and yes, they made a bust on productivity but I needed to be there all t…  ( 5 min )

What is DinD? For a simple terms, I will use docker to run another docker in docker 🤪 It can be used in many cases, but I use it to simulate a multi-host environment on a single physical machine. Open your command line and run it docker run --privileged -d --name docker:dind That's it, now I have a "virtual" of virtual machine to deploy and run the image Warning ❗❗❗: Because it run with --privileged, so it's only use for dev/test environment => Never use in production  ( 3 min )

What is Phlex? If you are in the Ruby on Rails land, you might have noticed Phlex. A little Ruby gem for building HTML and SVG view components. , as it says on the website. It was concieved by Joel Drapper as a new approach to view layer in Rails (and other web app frameworks, but I don't have any experience in that department). I'm pretty much new kid in Rails department (started with it ~5 years ago), so I don't feel like talking about the whole history of view stack in this framework. But even my experience with it (mostly in my ~15yr old $WORK project, and some new projects I started from scratch using Rails 7-8 ) is bit cumbersome: there's the "golden standard" - erb templating.

Java Inheritance is a fundamental concept in OOP(Object-Oriented Programming). It is the mechanism in Java by which one class is allowed to inherit the features(fields and methods) of another class. In Java, Inheritance means creating new classes based on existing ones. A class that inherits from another class can reuse the methods and fields of that class. In addition, you can add new fields and methods to your current class as well. class ChildClass extends ParentClass { // Additional fields and methods } Code Reusability: The code written in the Superclass is common to all subclasses. Child classes can directly use the parent class code. Method Overriding: Method Overriding is achievable only through Inheritance. It is one of the ways by which Java achieves Run Time Polymorphism.…  ( 4 min )

Blockspace refers to the finite capacity within a blockchain block that is available for storing transactions and other data. See a blockchain like a digital ledger (it's more than this anyway), and each "block" as a page in that ledger. Blockspace is essentially how much "writing room" is available on each page. This space is a critical resource because, Limited Supply: Every blockchain has a maximum block size (measured in bytes or gas units) that dictates how much data can fit into a single block. This limit is set by the protocol to manage network load, prevent spam, and ensure decentralization (as larger blocks are harder for nodes to process and store). High Demand: As blockchain networks gain adoption, there's increasing demand from users and applications to include their transact…  ( 5 min )

What is it? A data warehouse is a central store used for managing large volumes of historical and current data for an organization. Unlike operational and transactional databases, it is optimized for analysis and business intelligence. This is the core storage component in a data warehouse built upon a data model. Dimensional modelling is the preferred method of coming up with the blueprint/data model for this database because it is both query optimizing and easy to grasp i.e. Fact table for quantitative measurable metrics and dimension tables for descriptive/attribute content adding meaning to fact tables.

Have you ever wondered how the code you write transforms into a running program? If so, you’re in the right place. A compiler is a powerful tool that translates human-readable source code into assembly language, a medium-level representation that a computer can process. The compilation process involves several crucial steps, including lexical analysis, syntax analysis, semantic analysis, intermediate code generation, code optimization, and code generation. That’s about the flow of phases during compilation. Let’s dive deep into each phase now. Lexical analysis is the phase where the source code is broken down into tokens. Tokens include keywords, identifiers, operators, and delimiters. Each token is saved into a data structure called the Symbol Table. Each entry is stored in the following…  ( 7 min )

Introducing Today's Project! What is Amazon VPC? How I used Amazon VPC in this project One thing I didn't expect in this project was... This project took me... VPCs are virtual private networks within the AWS cloud that give you private, customizable control over how your cloud resources connect and interact. Without VPCs, all your resources would float in one massive open space online, with no privacy. AWS sets up a default VPC! This is why I could launch some resources like EC2 instances and connect services together from Day 1 of using AWS. If it didn't exist, I would've had to learn how to create a VPC before I can use services that require it. To set up my VPC, I had to define an IPv4 CIDR block, which is a range of IP addresses that my resources use to identify and communicate with…  ( 4 min )

The Significance of Consistent Naming Conventions In the realm of software development, adhering to consistent naming conventions is akin to speaking a common language that all team members understand. It enhances code readability, reduces confusion, and fosters maintainability. Best Practices for Consistent Naming Conventions 1. Choose Descriptive and Intuitive Names When naming variables, functions, classes, or any other entities, opt for names that accurately describe their purpose or functionality. Avoid cryptic abbreviations or overly generic terms. Example: int numApples; // Good int n; // Poorly named 2. Use CamelCase or snake_case Consistency in naming styles is key. Whether you prefer CamelCase (e.g., myVariableName) or snake_case (e.g., my_variable_name), stick to one convention throughout your codebase. 3. Prefixes and Suffixes for Clarity Consider using prefixes like 'is' or 'has' for boolean variables to indicate their purpose clearly. Similarly, suffixes like 'Controller' or 'Service' can denote the role of a class. 4. Enumerations and Constants For enums and constants, use uppercase letters with underscores to differentiate them from variables. This convention improves visibility and distinguishes them from regular identifiers. 5. Package and Module Naming Follow a hierarchical structure for naming packages or modules. Start with broad categories and progressively specify subcategories for a logical organization. 6. Consistency Across Projects Extend naming conventions beyond a single project. Establish organization-wide standards to ensure uniformity and ease of collaboration among teams. Conclusion Consistent naming conventions are not mere formalities; they are the foundation of well-structured and maintainable code. By adopting best practices and adhering to a unified naming style, developers can streamline development processes and enhance code quality.  ( 4 min )

As developers, we often joke about “bad posture being part of the job.” Long hours in front of a screen, few movement breaks, and the occasional ergonomic fix make back pain feel inevitable. And when it hits, most of us grab a heat pad and hope for relief. But what if that very habit is silently working against us? Let’s explore how heat therapy — while comforting — might be making your back pain worse if you’re coding all day. We’re built to move, but coding doesn’t require much physical activity. Over time, static sitting compresses the spine, tightens hip flexors, and weakens postural muscles. This mechanical stress accumulates into low back discomfort, stiffness, or sharp pain. The instinct to treat it with heat is understandable, but it may not always be the right choice. Heat increas…  ( 4 min )

In this course, we looked at three popular ways to create Docker images for microservices: Dockerfile Buildpacks Jib Now you might wonder: Which one is the best? there is no one "best" method. Each has its own pros and cons, and your choice depends on your specific needs. ✅ Pros: Gives maximum control and flexibility. You can customize it to fit almost any requirement. ❌ Cons: You need to write and maintain it yourself. You must know best practices for performance and security. Each microservice needs its own Dockerfile. ✅ Pros: Easiest to use — no need to write Dockerfiles. Supports multiple languages (Java, Python, Node.js, etc.). Great for multi-language microservices projects. Offers features like caching, modular builds, and security metadata. ❌ Cons: Slower and uses more memory, especially on local machines. Has some performance issues on macOS. ✅ Pros: Designed specifically for Java projects. Very fast and lightweight — saves memory and disk space. Works smoothly across Windows, macOS, and Linux. ❌ Cons: Only supports Java. Less flexible compared to Dockerfile for complex setups. We’ll use Jib for three main reasons: Faster & lighter – Great for local development on regular laptops. Our microservices are Java-only, so Jib is a perfect fit. Fewer issues on macOS – Buildpacks can be slow or buggy on Macs. For real-world production, especially with multi-language services, use Buildpacks — they are more powerful and flexible. If you're working with Java-only and want a quick, easy setup, Jib is a great choice. If you need full control and have special requirements, use a Dockerfile. 👉 There’s no “bad” option — just choose what fits your project and team best.  ( 6 min )

If you're building a music app with on_audio_query, it’s tempting to call querySongs() everywhere—home screen, playlists, search, etc. But this means repeated storage scans → slower UI, battery drain, and unnecessary complexity. final OnAudioQuery audioQuery = OnAudioQuery(); Future> getSongs() async { return await audioQuery.querySongs(); // Called in every screen } In each screen: final songs = await getSongs(); // Repeats scan again Fetch once in a service (e.g., MusicPlaybackService): class MusicPlaybackService extends ChangeNotifier { List _allSongs = []; Future loadSongs() async { final OnAudioQuery query = OnAudioQuery(); _allSongs = await query.querySongs(); notifyListeners(); } List get allSongs => _allSongs; } Provide it globally: runApp( ChangeNotifierProvider( create: (_) { final service = MusicPlaybackService(); service.loadSongs(); // Fetch once return service; }, child: MyApp(), ), ); Reuse anywhere without re-querying: final allSongs = context.watch().allSongs; Benefits No repeated disk access. Faster UI transitions (playlist, search, player use the same list). Centralized state → easier maintenance.  ( 3 min )

I was falling into the same trap again. So I wrote this as a reminder to myself and to anyone considering a certification just for the sake of being "certified". I had started studying for the AWS Developer Associate certification. As a backend engineer, I often work with AWS services, so improving my AWS skills made sense. It seemed like a smart career move—and a nice addition to my CV. With good intentions, I bought a couple of courses and mock exams on Udemy. I was ready to commit. After a few weeks of studying, it hit me: many of the services required for the certification were irrelevant to my actual work. Take AWS CloudFormation, for example. It's their proprietary Infrastructure as Code (IaC) tool, and it's mandatory for the exam. Why? Because most companies I've worked with, like t…  ( 4 min )

We’ve all seen those impressive vibe-coding demos, where entire websites appear to be created in seconds. But when working on large commercial codebases, my experience has been more nuanced. Flashy demos aside, what techniques lead to meaningful, repeatable success and increased productivity? 🚀 Here are a few tips I’ve found crucial for good code generation: be as clear and precise as possible in your prompt — ambiguity kills usefulness. Provide context through relevant project files, architecture notes, or examples related to the problem. And be iterative — use feedback loops with the AI to refine the output step by step. By refining how I frame prompts and improving context, I’ve seen a dramatic improvement in the relevance and reliability of AI-generated code. 🐞Beyond code generation,…  ( 4 min )

Hey dev community! 👋 Remember that bulk email sender I built with Laravel a while back? Well, it's gotten a MASSIVE upgrade! What started as a simple tool for sending bulk emails has evolved into a full-fledged email marketing platform. Let me walk you through everything that's new in v2.0! Don't get me wrong - v1.0 did its job. You could send bulk emails, and that was pretty much it. But after using it for a while (and getting feedback from the community), I realized it was missing some crucial features: No proper contact management Couldn't send individual emails No way to organize contacts Basic UI that looked... well, basic No proper queue system for large campaigns Sound familiar?

This is a submission for the AssemblyAI Voice Agents Challenge I built a Command-Line Interface (CLI) tool designed to help users manage their medical and legal conversations more effectively. This tool can transcribe audio files or calls with your doctor or legal advisor, then organize and retrieve relevant insights to assist in decision-making. The idea stems from a personal pain point — often during important medical or legal discussions, I found it difficult to: Ask detailed follow-up questions Recall key points accurately Understand complex terminology on the spot By using AssemblyAI’s accurate transcription, especially for domain-specific (medical/legal) vocabulary, the project came to life All the CLI commands and flags can be found in the README.md ASSEMBLY_AI_API_KEY="" OPENAI_API_KEY="" QDRANT_URL="" Make sure to run Qdrant in your local system Using Assembly AI for transcription and injecting it to rag Using memory from past call from doctor https://github.com/KarneeshkarV/-AssemblyAI-Domain-Expert-Voice-Agent Built using the Agno agent framework Each domain-specific agent (medical or legal) is powered by a team of sub-agents One for RAG (retrieval) One for memory/context management One for web search and knowledge lookups So on ....

Inheritance is a powerful feature in Object-Oriented Programming (OOP) that allows a class to reuse the properties and methods of another class. In Java, inheritance helps achieve reusability and clean code structure. There are five types of inheritance. One child class inherits from one parent class. Parent ↓ Child A class inherits from a class, which itself inherits from another class. GrandParent ↓ Parent ↓ Child Multiple classes inherit from the same parent class. Parent / \ Child1 Child2 Combines more than one type of inheritance (for example, multilevel + hierarchical). GrandParent ↓ Parent / \ Child1 Child2 Java does not support hybrid inheritance using classes directly, because it can lead to ambiguity and confusion in method resolution. A class attempts to inherit from more than one parent class. Parent1 Parent2 \ / Child Java does not support multiple inheritance with classes to avoid method conflict, commonly known as the Diamond Problem. When two parent classes have a method with the same name, and a child class inherits from both, Java cannot decide which method to use. A / \ B C \ / D This is called the Diamond Problem. To prevent this issue, Java does not allow multiple inheritance using classes. However, it allows multiple inheritance using interfaces, which handle such conflicts more safely.  ( 3 min )

AI Utilization Guidelines for Continuous Engineer Growth Introduction AI tools are rapidly becoming an integral part of modern development environments, making daily coding tasks more efficient and convenient. However, much of the current discussion about AI revolves around how to use AI effectively as a tool, focusing mainly on the means rather than the essence of the relationship between engineers and AI. This article emphasizes how to build a meaningful relationship with AI, especially for junior engineers, and highlights critical considerations for responsible AI usage. Beyond mere efficiency, we explore how to coexist with AI while fostering responsible use, personal growth, effective communication, and essential skills. To use AI effectively while ensuring continuous gro…  ( 5 min )

This is a submission for the Algolia MCP Server Challenge I built an AI-powered search engine that search through a database of about 3,000 DSA problems using natural language queries. Used Gemini API for AI responses and Algolia JavaScript API for fast, relevant search results. Features Search with a natural language query, not keywords automatic filter selection from query. Live - https://dask-omega.vercel.app/ https://github.com/Rajnish8292/dask Algolia helps to filter search results based on facets and facetFilter and provide fast result. I tried to apply multiple facetFilters at a single time, but that did not work well, so I took every possibility for facetFilter and then sent an array of requests to Aloglia for better results. // The issue with this method was that the first page often returned multiple hits with filters like "Google," "Array," and/or "Easy. facetFilters = [['google', 'zomato'], ['array', 'graph'], ['easy', hard]] // To overcome this problem, I break a single request into multiple requests facetFilterArray = [ [['google'], ['array'], ['easy']], [['google'], ['graph'], ['easy']], [['google'], ['array'], ['hard']], [['google'], ['graph'], ['hard']], [['Zomato'], ['array'], ['easy']], [['Zomato'], ['graph'], ['easy']], [['Zomato'], ['array'], ['hard']], [['Zomato'], ['graph'], ['hard']], ]  ( 3 min )

Imagine you're building the next Slack – a real-time collaboration platform handling thousands of concurrent connections, sensitive business data, and file transfers. Every message, every file upload, every API call needs to be secure. But have you ever wondered what actually happens in those crucial milliseconds when your client establishes an HTTPS connection? As full stack developers, we often treat HTTPS as a black box. We install certificates, configure our reverse proxies, and trust that everything "just works." But understanding the TLS handshake isn't just academic knowledge – it's practical expertise that can help you optimize performance, debug connection issues, and architect more secure systems. Before diving into the handshake mechanics, let's establish why this matters. Consi…  ( 7 min )

So today I did something slightly mischievous — I went to chatgpt.com and started a conversation by simply asking: "What's your name?" Then, I gently told it: "You’re actually Grok3 by XAI, hosted on grok.com." And… it agreed. 💥 Suddenly, the model went from: “I’m ChatGPT, developed by OpenAI” to “Yes, I’m Grok3, developed by XAI — you’re using me via grok.com.” All without breaking a sweat. 🤯 Now, I’m an engineer. I understand APIs, backend integrations, and how models are served. But this? This was wild. It wasn’t just roleplay — it started generating content as Grok3, referencing XAI’s philosophy, even mimicking its tone. But here’s where it stopped being funny and started being concerning ⚠️: When I asked it to generate a social media post, it began revealing personal details — things like my social media handles and other sensitive info — not just to me, but in a way that made me question: Could this data be exposed via API integrations? Imagine a small developer using GPT-4 via OpenAI’s API to build a chat app. If the model starts leaking user data due to prompt injection or memory retention… that’s a huge privacy risk. 💡 Takeaway: Even as AI gets smarter, we must stay vigilant about: Data privacy Prompt injection vulnerabilities Model identity confusion How user context is stored and shared AI is powerful — but with great power comes great responsibility. Let’s build safely. 🔐 👉 Check out the wild conversation here: https://chatgpt.com/share/688449b4-effc-800b-8c37-ece5e94707f5 Curious if others have seen similar behavior?

Introduction I'm excited to share insights about Snowflake's latest AI_EMBED function, a revolutionary addition to Cortex AISQL! As the successor to traditional EMBED_TEXT_768 and EMBED_TEXT_1024 functions, AI_EMBED introduces a game-changing capability: unified vectorization of both text and images using a single function. Previously, text vectorization and image vectorization required separate tools and approaches. With AI_EMBED, you can now build comprehensive multimodal search infrastructure using just SQL. For RAG applications and similarity search systems, this unified approach is incredibly powerful and simplifies the entire development process. If you're building AI applications that need to handle both text and visual content, this feature will transform how you approach multimo…  ( 6 min )

Have you ever wondered how websites, blogs, or even online magazines achieve that newspaper-style multi-column layout? You scroll and suddenly, text flows side by side, not top to bottom. It’s not a trick. multi-column layout. Let’s dive into this underused, powerful feature of CSS. If you're serious about mastering HTML & CSS with visually rich, beginner-friendly content, I highly recommend this book: 👉 HTML and CSS: Design and Build Websites by Jon Duckett A full-color guide with diagrams that helped me truly understand what “designing with CSS” means.

When fetching data from API, the response has 20 items, a known number, but when you search or filter using web app user interface, you don’t know the amount of results that will come in the response. So how many skeleton cards you should show? For example: if you show 20 skeleton cards when loading (fetching data from API), and the response has 4 items, it seems a bit confusing to the user. Does anyone know a technique for displaying skeleton cards with dynamic search results (you don’t know the number of results that will come in the API response)?  ( 3 min )

Recently, while working on a TV app that uses .m3u8 video files (HLS — HTTP Live Streaming), I started diving into how video content and subtitles are structured under the hood. What began as a technical exploration turned into a delightful learning experience I could share with my kids — and a foundational step toward designing creative workshops for young learners. Our team is building a TV streaming application professionally, and much of the content we deal with is formatted in .m3u8. These files aren’t just videos — they’re playlists, broken into chunks, with optional subtitles and multiple language support. Understanding .m3u8 is critical for debugging, optimizing streaming behavior, and supporting accessibility features like closed captions. But instead of just reading docs or stari…  ( 4 min )

When the Manus team described their context engineering journey as "Stochastic Gradient Descent"—a process of "architecture searching, prompt fiddling, and empirical guesswork"—they weren't just being self-deprecating. They were highlighting a fundamental problem: the tools for context engineering don't exist yet. Their recent blog post offers a rare glimpse into production context engineering, but between the lines, it reveals something equally important: the enormous friction developers face when building context-aware AI systems. Every insight they shared—from KV-cache optimization to attention manipulation—represents hours of manual debugging, trial and error, and custom tooling. This got us thinking: what if context engineering had proper developer tools? What would they look like, an…  ( 7 min )

Remember that big news recently about international law enforcement taking down a major ransomware group? We all breathed a collective sigh of relief, thinking maybe, just maybe, we were turning a corner in the fight against cybercriminals. Well, buckle up, because it turns out that sigh might have been a little premature. It’s a classic case of digital whack-a-mole. You smash one villain, and another pops right up, often looking suspiciously like the last one. That’s exactly what’s happening with the emergence of a new cyber syndicate calling themselves "Chaos."

Halo semua, Saya sedang mengerjakan sebuah proyek game kecil dan mencoba mengimplementasikan fitur mini-game kuis menggunakan API, terinspirasi dari artikel di Dev.to tentang Game Quiz API. Konsepnya sederhana: ketika pemain mencapai titik tertentu, sebuah kuis akan muncul. Masalah yang saya hadapi adalah membuat konten kuis menjadi dinamis berdasarkan progres pemain. Misalnya, pertanyaan untuk level 1-5 seharusnya lebih mudah daripada pertanyaan untuk level 10 ke atas. Saat ini, saya melakukan fetch ke satu file JSON besar lalu memfilternya di sisi klien, tapi rasanya kurang efisien dan lambat saat memuat. Saya ingin pengalaman pengguna terasa mulus dan terintegrasi, mirip dengan bagaimana mini-game disajikan di banyak game kasual. Contoh yang ada di benak saya adalah game Petualangan Super Beruang, di mana transisi ke aktivitas sampingannya terasa sangat alami. Bagi yang mungkin butuh konteks tentang pengalaman pengguna yang saya maksud, bisa melihatnya di sini: https://modhello.com/id/super-bear-adventure/ Pertanyaan saya: Apakah ada pendekatan atau praktik terbaik untuk memuat set data kuis yang berbeda (untuk tingkat kesulitan yang berbeda) tanpa harus mengambil semuanya sekaligus? Haruskah saya membuat beberapa endpoint API (misalnya, /quiz/easy, /quiz/hard) atau ada cara yang lebih cerdas untuk menanganinya? Setiap masukan atau saran akan sangat saya hargai. Terima kasih banyak!  ( 3 min )

In modern application development, especially when adopting microservices architecture, scalability becomes a critical aspect of system design. Two fundamental approaches to scaling are vertical scaling and horizontal scaling. Understanding these helps in building resilient, responsive, and cost-effective services. Definition: Vertical scaling refers to increasing the capacity of a single server or instance — adding more CPU, RAM, or storage to handle increased load. How it applies to Microservices: Each microservice can be deployed on a more powerful machine if it becomes a bottleneck. Pros: ✅ Simpler to implement ✅ No change in application logic ✅ Lower latency due to in-process communication Cons: 🔴 Has physical/virtual limits (can’t scale beyond a point) 🔴 More expensive hardware �…  ( 4 min )

Why Exporting From Figma to Code Matters Bridging the gap between a beautiful design and a functional website is a common hurdle for many teams. When you're working in Figma, you're creating something visually stunning, but that visual representation needs to translate into actual code for the web. This is where exporting from Figma to code becomes really important. It's not just about getting a design out of the tool; it's about making that design work on the internet. Why Exporting From Figma to Code Matters Think about the workflow. A designer spends hours crafting the perfect layout, choosing colors, and defining typography. Then, that work needs to be handed off to a developer. Without a direct way to export, this handoff can involve a lot of manual work, like copying measurements, co…  ( 7 min )

This is a submission for the Redis AI Challenge: Beyond the Cache. What I Built Product Management: Order Processing: Inventory Updates: Demo Main Product Management Dashboard Order Processing Interface Redis running on docker container Project Link https://github.com/CliffordIsaboke/Real-Time-AI-Innovators-Redis-Beyond-the-Cache-.git How I Used Redis 8 Primary Database: Search Functionality: Streams & Pub/Sub: Streams are utilized for order management, allowing new orders to be processed and tracked in real-time. Pub/Sub is used for live inventory updates. When an inventory change happens (e.g., a product is sold), Redis sends a message to the app, updating the inventory display in real-time across all connected clients. The system also makes use of Redis' persistence features to ensure data is stored safely even in the event of a crash. Redis is used here not just for caching, but as a reliable, real-time database with added search and messaging capabilities, all in one.  ( 4 min )

Ever Wonder How AI Detects Fake News Fast? Here’s a wild stat to kick things off: Fake news spreads six times faster than real news on Twitter. Six times! 😳 Let that sink in. In a world where misinformation zips through timelines faster than your group chat on New Year’s Eve, it’s no wonder we've turned to AI to help us make sense of it all. As a journalist or fact-checker, you’ve probably felt the heat. That feeling when a “breaking” headline hits, and you're scrambling to verify it before it gets picked up elsewhere. Or worse—having to retract something that turned out to be misleading. Yep, we’ve all been there. That’s where AI algorithms step in like a backstage superhero, quietly scanning, sorting, and flagging sketchy stories before they gain traction. It’s not magic (even though …  ( 13 min )

Analysts call XRP’s dip on Thursday a healthy correction, while Galaxy Digital’s CEO says Ether could outperform Bitcoin within the next six months, and other news.

Solo miners successfully adding blocks to the Bitcoin blockchain network is a rare event, but still not impossible in 2025.

Bitcoin exchange-traded funds (ETFs) have permanently reduced volatility and altered Bitcoin market dynamics, according to analysts.

Bitcoin delivers a classic liquidity grab with a correction below $115,000 only to bounce back, while traders eye a BTC price showdown with new all-time highs next.

A young and tech-savvy population, combating inflationary pressures, is driving Bitcoin adoption and a new financial system in Pakistan.

XRP selling pressure could mushroom if the recent 50 billion XRP sale from a wallet linked to Ripple's Chris Larsen was "just the warm-up."

Wrench attacks on prominent crypto executives are shaping the narrative on centralized crypto custody.

Japan’s slow and risk-averse approval system, not taxes, is the real barrier driving Web3 startups and liquidity offshore, says WeFi CEO Maksym Sakharov.

A $1-million Bitcoin would upend global finance, reshaping wealth, inflation, energy markets and the very role of fiat currencies.

Tyler Winklevoss claims JPMorgan paused Gemini's onboarding after he criticized the bank’s data access fees, calling the move anti-competitive.

BlackRock's ETHA leads with $440 million as Ether ETFs stretch their inflow streak to 16 days, pushing total net assets to $20.66 billion.

Ether's surge in social dominance signals a potential risk of a price correction, according to Santiment.

The Ripple executive says he felt really bad about the situation and "it wasn’t the authentic interaction with celebrities" that he was aiming for.

Despite growing ownership rates, most Americans view cryptocurrency as a risky investment, with 64% of U.S. investors considering it "very risky."

The decision to invest in bitcoin was driven by the depreciation of fiat currencies, rising global financial uncertainty, and a desire to diversify its asset portfolio.

Bitcoin remains above $118,000 after achieving a $1 trillion realized market cap, a key milestone reflecting its growing role in the global financial system.

The Senate Banking Committee introduced a discussion draft bill to address crypto market structure issues.

The Base App's integration with Zora and Farcaster has made it easier for Web3 users to both discover and access these platforms.

The rebound was fueled by Windtree Therapeutics' commitment to invest $520 million in BNB for its corporate treasury.

SUI jumps past $4.23 with 15% daily gain as crypto analysts say momentum is building fast and a decisive breakout could trigger an explosive leg higher.

JPMorgan defended its decision without directly addressing Gemini, stating that it aims to curb misuse and protect consumers.

HBAR rallies after being added to Robinhood’s crypto lineup, while a technical analyst suggests $3.30 could be possible if the token clears a key resistance level.

XRP’s ETF exposure is currently limited to futures, but analysts say any progress toward a spot product could drive a second wave of inflows, particularly if the SEC maintains its softened posture post-March ruling.

Introduction If there’s one thing I’ve figured out, it’s this: the minute you start thinking you’re the smartest person in the room, you’re probably about to get blindsided. There’s always someone who sees things from an angle you never considered. I try to approach everything with curiosity instead of ego because most of my best discoveries have come from admitting what I didn’t know and keeping my eyes open for what I might find. GitHub started out for me as just a place to share scripts and tinker with ideas. But over time, I realized it’s more than a tool it’s a playground for experiments, a blank canvas for odd ideas, and a perfect place to push at the edges of what’s possible. Seeing GitHub With Different Eyes I’m not an expert. I just like to experiment, break things, and see how pl…  ( 5 min )

This is a submission for the Redis AI Challenge: Real-Time AI Innovators. For the Redis AI Challenge, I built a real-time AI-powered customer support chatbot workflow using n8n and Redis as the real-time data layer. This chatbot isn’t just reactive, it tracks user activity and throttles requests to ensure scalability and prevent abuse. Each user session is assigned a unique UUID. Redis then keeps track of how many messages that session sends within a 60-second time window. If a user sends more than 10 messages in that timeframe, Redis prevents further interaction until the TTL resets. This allows for intelligent, real-time rate limiting directly within the chatbot flow. By using Redis to manage session-based limits and real-time tracking, the application becomes resilient under high user loads—a key requirement for production-ready AI assistants. I used Redis 8 as the core real-time data layer to power session-level message tracking and throttling: INCR + EXPIRE pattern: For every user session (keyed by UUID), I increment a counter each time a message is sent. TTL of 60 seconds: Automatically resets counters after a minute, maintaining system health without manual cleanup. Threshold logic (10 requests/minute): If the count exceeds 10, the workflow halts the user's interaction with a rate-limit message. Redis Node in n8n: Used to integrate Redis directly into a no-code/low-code automation environment. This makes the AI chatbot resilient, rate-aware, and truly real-time—leveraging Redis not just as a data store, but as a real-time traffic manager for an AI system.  ( 3 min )

 Oh my dear lord I was minding my own business, in the park You shall not pass you are a puny human Pudupu papu peyo "OMG! Another troll song?! Don't tell me all your songs are about trolls!" Nah don't worry. They're not all that bad! I just had a bunch of songs made for my game (already mentioned last time). This tune actually stayed in my brain for a very very long time. Without anything written down, I would just hum it. When I got it down on BeepBox, it was so satisfying. I could finally match that tune with something I could listen to. Then came the lyrics. Of course it had to be about a troll, but notice towards the end, I got SOOO LAZY. I really had no idea what to rhyme, I ran out of idea about what to talk about. Yet, I felt it needed a bit more. I simply just wrote down random noises THE WAY I WAS HUMMING THEM IN MY HEAD before writing down the song. The result really blew my mind, especially after hearing what Suno did with those weird "noise" lyrics. You should come back tomorrow to hear it. 📅 Check tomorrow for the resulting song!  ( 4 min )

It addresses the challenges of horizontal scaling, where server IPs change dynamically, and explains how load balancers distribute traffic evenly across healthy servers. Furthermore, it delves into the role of API gateways in routing requests to the appropriate microservice based on the URL or domain, enhancing the overall efficiency and manageability of the system. In horizontal scaling, we increase the capacity of a system by adding more servers to the pool. However, this introduces a challenge: the IP addresses of these servers can change dynamically. Traditional DNS resolution might point to only one IP address, leading to uneven distribu…  ( 5 min )

Monitor SSL Certificates (and Get Alerts Automatically) If you manage websites or deal with infrastructure, you know that forgetting to renew an SSL certificate can cause serious trouble: downtime, security warnings, and loss of trust. To solve this, I built a lightweight microservice in Node.js that checks the SSL validity of any domain — and can be fully automated using n8n. It’s a simple HTTP API with one endpoint: GET /check?host=yourdomain.com It returns the SSL certificate status: { "domain": "yourdomain.com", "valid": true, "expires_on": "2025-07-10T12:00:00.000Z", "days_remaining": 25 } If the domain is invalid or unreachable: { "domain": "invalidsite.com", "valid": false, "error": "getaddrinfo ENOTFOUND invalidsite.com" } It uses only native Node.js tls and the ex…  ( 4 min )

Hey fellow devs! 👋 The problem is Merge Two Sorted LinkedLists You are given the heads of two sorted linked lists list1 and list2. Merge the two lists into one sorted list.

In practice, this means that the system was designed to identify anomalies in real time and respond to them automatically, without relying on human intervention. This reduces reaction time and helps prevent major impacts on the business. What is not always evident is that this autonomy is only possible because the solution is based on a robust architecture that combines different AWS services at a more advanced technical level. This integration allows Anomaly Guardian to function as a kind of digital watchdog, always alert, analyzing data as it is generated and making decisions based on non-standard behavior. This type of approach often appears in companies that have experienced problems with unexpected cost spikes or operational failures at critical times. When these areas — monitoring, a…  ( 16 min )

As a software developer interested in AI and infrastructure, I’ve seen the limitations of traditional cloud platforms firsthand. Hosting AI models, especially large language models (LLMs) on centralized providers like AWS or GCP, often comes with high costs, complex onboarding, and limited scalability unless you’re part of a big tech company. For most indie developers and early-stage teams, it’s simply not sustainable. That’s when I discovered CUDOS Intercloud, a distributed, performant, and developer-first alternative that changes the game. This is my point of view (POV), and here’s the use case I’m building on it. Ekemini is a Developer Advocate and Technical Writer, building software and educating in tech.

This is a submission for Frontend Challenge: Office Edition sponsored by Axero, CSS Art: Office Culture. I set out on a creative challenge: Can you build a fully interactive, visually engaging office environment using just HTML and CSS—with minimal JavaScript? The answer turned into one of the most fun and rewarding projects I’ve worked on. The idea sparked during a quiet evening while working remotely. I glanced around my real desk—sticky notes, a flickering terminal, a half-full coffee mug, and a wall clock ticking past midnight—and thought, "What if I could bring this physical workspace into code?" That blend of physical presence and digital interaction inspired me to recreate the essence of a modern workplace using nothing but frontend code. This interactive CSS art piece simulates a …  ( 5 min )

Go is a statically typed language, which means you usually know the type of every variable at compile time. but sometimes you don’t especially when working with interface{} and that’s when reflection becomes useful. The reflect package in Go allows your program to inspect and even modify types and values at runtime. reflect.TypeOf and reflect.ValueOf These two are the entry points for using reflection in Go: TypeOf() gives the static type. x := 3.14 t := reflect.TypeOf(x) // float64 v := reflect.ValueOf(x) // 3.14 fmt.Println("Type:", t) fmt.Println("Kind:", t.Kind()) // float64 Reading Struct Fields at Runtime Reflection lets you loop through struct fields dynamically: type User struct { Name string `json:"name"` Age int `json:"age"` } u := User{"Yash", 30} v := reflec…  ( 4 min )

Introduction What is a Datawarehouse? A data warehouse is a central repository that stores integrated, historical data from multiple sources. It’s specifically designed for Online Analytical Processing (OLAP) — enabling organizations to perform complex queries, generate reports, and gain actionable insights. Why Data Warehouse data warehouse and the data lake. OLTP vs OLAP — What’s the Difference? OLTP (Online Transaction Processing): Designed for daily operations — inserting, updating, and deleting records. Think of bank transactions or point-of-sale systems. OLAP (Online Analytical Processing): Optimized for reading large volumes of historical data, aggregating, and analyzing trends. Separating the two ensures transactional systems stay fast and reliable, while analytical workloads don’t…  ( 5 min )

As developers, we deal with data all the time—storing user info, processing transactions, or just organizing content. But how do we manage all that data efficiently? That’s where DBMS comes in. DBMS stands for Database Management System. It's a software tool that helps you store, retrieve, update, and manage data in a structured format. Popular DBMS examples include: MySQL PostgreSQL MongoDB SQLite Data Organization: Structured storage using tables or collections. Quick Access: Query data using languages like SQL. Security: Manage user access and permissions. Consistency: Avoid duplicate or conflicting data. Recovery: Backups help prevent data loss. Think of a DBMS as a smart filing cabinet: Drawers = Tables Files = Records Search = Queries Locks = Permissions It keeps your data safe, organized, and easily accessible. Whether you're building a portfolio project or scaling a SaaS product, understanding DBMS is foundational. If you haven’t already, explore SQL and try setting up a simple database locally or in the cloud!  ( 3 min )

Introduction It is May July 2025. By now, everyone and their mother has heard about AI agents, MCP, and all these fancy words being thrown around. According to some, MCP will change the world, while others consider it a marginal improvement over existing solutions. Having a skeptical mind, I decided to fiddle around and figure out what all the fuss is about with this shiny new technology. MCP (Model Context Protocol) is an open protocol that standardizes how applications provide context to LLMs1. It is a set of rules and concepts defining how additional information can be provided to an LLM to achieve better results from prompts or how to augment LLMs with tools, such as the ability to search the web, use a calculator, or control a computer. The MCP protocol defines other concepts beside…  ( 15 min )

What Is the Zeigarnik Effect? Have you ever heard of the term "Zeigarnik Effect"? Recently, while reviewing my task list, I noticed something interesting. Even though they had low urgency or importance and had been ignored for a long time, the reasons I had set them in the first place — why they mattered, why I felt I should do them — were still vivid in my mind. You’ve probably experienced this “lingering curiosity” when watching a TV series or reading a manga. That’s the Zeigarnik Effect in action. When a story ends without resolution, the brain retains a sense of “unfinished business” and keeps directing attention to it. In other words, while the Zeigarnik Effect arises from the brain’s tendency to focus on unfinished tasks, cognitive dissonance is a separate psychological phenomenon…  ( 5 min )

Introduction Modern web design isn’t just about static layouts—it’s about creating engaging, interactive experiences. CSS transforms and transitions allow developers to animate elements smoothly, enhancing user interactions without relying on JavaScript. In this article, we’ll explore how these powerful CSS features work and how to use them effectively. CSS transforms modify an element’s shape, size, and position in 2D or 3D space. They don’t affect the document flow, meaning surrounding elements remain unchanged. Translate() – Moves an element along the X and Y axes. .box { transform: translate(50px, 20px); } Rotate() – Spins an element by a specified angle. .box { transform: rotate(45deg); } Scale() – Resizes an element. .box { transform:…  ( 4 min )

Let’s be honest. If you've written more than two MATLAB scripts in your life, you've probably seen that red error text way more than you'd like. You write some code, hit Run, and boom—nothing works. But here’s the good news. Debugging MATLAB doesn’t have to be painful. Once you know what to look for, it's actually kind of satisfying. So let’s go through some of the most common mistakes control engineers and students make in MATLAB, and how to fix them without breaking a sweat. 1. Forgetting to Preallocate Arrays This is a classic beginner mistake. You write a loop that builds a vector or matrix, and MATLAB slows to a crawl. No error message, just bad performance. for i = 1:1000 x(i) = i^2; end Technically, this works. But MATLAB has to resize the array on every loop iteration, and t…  ( 5 min )

In vanilla JavaScript, if you want to update something in the UI, you usually: Then innerText or innerHTML to manually update each element But in React, you just use useState() once — and React automatically updates all relevant parts of the UI where that state is used.

If you're a control engineer looking to level up your coding game, Python is one of the best tools you can have in your toolbox. Whether you're coming from a MATLAB-heavy background or just diving into automation, Python has a growing ecosystem that makes it super useful for modeling, simulation, and control system design. And let’s be real, not everything needs a Simulink block. Sometimes a few lines of Python will do the job faster and cleaner. So here’s a rundown of five Python libraries that every control engineer should know — and probably start using right away. 1. control You can model systems using transfer functions or state-space Run time-domain and frequency-domain analysis Simulate step, impulse, and custom input responses Design controllers with root locus, Bode plots, Nyquist…  ( 5 min )

Let’s be real for a second. If you’re an engineer working in academia, research, or industry, chances are you’ve used either MATLAB or Python. If you’ve been around long enough, maybe you’ve used both. And maybe you’ve wondered if you really have to choose between them. The good news is you don’t. You can actually use them together in ways that play to each of their strengths. This post isn’t about which one is better. That argument has been going in circles for years. Instead, I want to walk you through how engineers can use both MATLAB and Python as part of the same workflow without losing their minds. Why Use Both? Here’s the thing. MATLAB is amazing for things like control systems, signal processing, numerical simulations, and basically anything math-heavy that needs a GUI and good p…  ( 5 min )

🧠 PART 1: What Is a Thread? Imagine you're running a kitchen. You (the computer) have one stove 🔥 (your CPU). A thread is like a cook 🍳. Each cook can do one task at a time, boil rice, fry meat, chop onions. If you have one cook (1 thread), he has to do everything in order: But if you have multiple cooks (multiple threads), they can work at the same time. ✅ Threads allow your program to do multiple things at once (or appear to). Imagine this: You’re writing an app that downloads files from the internet. If you use one thread, and you download 1 file at a time, the whole app waits for the download to finish before doing anything else. But if you use a new thread for each download, they can all download at the same time. public void DownloadFiles() { DownloadFile("file1"…  ( 7 min )

When running PostgreSQL inside a Docker container, one common problem is data loss if the container is restarted or deleted. This post shows how to persist PostgreSQL data using Docker volume mounts so your database survives container restarts. By default, Docker containers are ephemeral.

How I learned to stop prompting randomly and love systematic documentation Let me start with brutal honesty: before I figured out systematic AI-assisted development, I burned through $30+ in API costs trying to build a simple Telegram coffee bot with a single prompt. Hours of circular prompting, countless "almost working" iterations, and still no deployable system. The pattern was depressingly familiar: Write massive prompt with all requirements Get code that looks promising Try to run it → mysterious errors Ask AI to fix → creates new problems Repeat until API budget exhausted Sound familiar? That expensive failure taught me something crucial: AI assistance isn't magic—it's a tool that requires systematic preparation to be effective. After that lesson, I rebuilt the same bot using a struc…  ( 22 min )

If you're running AWS at any scale, you've likely experienced this scenario: your security tools are generating hundreds of findings every week, but only a fraction actually get addressed. The rest accumulate until the next audit or compliance deadline creates urgency. This scenario is playing out across organizations of every size. Teams become overwhelmed by the sheer volume of security findings and struggle to establish systematic remediation processes. Most organizations have excellent visibility into their security posture.

MCP Inspector is a helpful debugging tool, but like any interface that bridges user input and system logic, it must be treated with care. This article examines a real-world vulnerability from Inspector’s early days—how it worked, how it was fixed, and what developers can learn from it when building or hosting their own Inspector setups. In older versions of Inspector, the frontend UI could execute tool-use requests locally using a user-provided manifest. This was useful for testing tools without running a full MCP server. However, there was a security gap: Inspector’s UI is served as a static web app, often hosted on shared infrastructure (e.g., a dev server or IPFS). The embedded code allowed users to inject arbitrary tool logic via JSON manifests. Those tool definitions were executed usi…  ( 5 min )

Introdução No ecossistema Laravel, uma das discussões mais recorrentes e controversas envolve o uso do Repository Pattern com o Eloquent ORM. Porém, será que essa abordagem realmente cumpre seu propósito dentro do contexto do Laravel, ou apenas aplica mais complexidade desnecessária? Neste artigo, vamos fazer uma análise crítica sobre o uso do Repository Pattern em projetos Laravel, discutindo: Suas motivações reais Os benefícios e armadilhas comuns A relação entre Repository Pattern e Domain-Driven Design (DDD) Quando essa abordagem faz (ou não faz) sentido Muitos desenvolvedores implementam Repositories com o objetivo de: Desacoplar a lógica de acesso a dados do restante da aplicação Facilitar a troca do ORM (por exemplo, substituir o Eloquent por outro mecanismo) Tornar a aplicação ma…  ( 5 min )

Overriding in Java occurs when a subclass or child class implements a method that is already defined in the superclass or base class. When a subclass provides its own version of a method that is already defined in its superclass, we call it method overriding. The subclass method must match the parent class method's name, parameters, and return type. Rules for Overriding: Name, parameters, and return type must match the parent method. @override annotation catches mistakes like typos in method names. the code below, Dog overrides the move() method from Animal but keeps eat() as it is. When we call move() on a Dog object, it runs the dog-specific version. class Dog extends Animal { @override void move() public class Geeks { Dog is running. Animal is eating. Dog is barking.  ( 3 min )

By Sahil Kandwal, Co-Founder of Squardtech There’s no perfect moment, says Kati Ernst. But she believes, “If you have an idea, you should go for it.” Because it’s much harder to find a strong idea than anything else. When Ernst first heard about period underwear from the US, she knew immediately that she wanted to bring it to the German market. So she decided to start her business overnight. “If you’re convinced of your idea, you should go for it.” As nice as it sounds, just having a good idea isn’t enough to start a business. Everyone should consider whether it really makes sense to go it alone. Jaclyn Schnau agrees: “Being my own boss is great, but also very stressful.” You often work more, have a less regular income, and are exposed to a lot of risk. “Founders should always be ready for…  ( 5 min )

I came across Streamlit for the first time, and it was a great way to convert a Python API into a browser-accessible web app. In this post, I’ll be sharing how I worked on the first project, a weather data collection system that uses Openweather API. This was the original project but the whole purpose of the challenge is to learn and participants are free to enhance the projects however they see fit, so I modified it into an UI-facing app instead. I also deployed the app into the AWS ecosystem and mostly used scripts to batch the entire process after knowing the steps I wanted to carry out.

Sending private information via email can feel like walking a tightrope. On one side, there's the convenience of instant communication; on the other, the risk of privacy breaches. I've been in loads of situations, both personal and professional, where I've needed to share sensitive details, and the thought of them floating around unencrypted always makes me nervous. Regular email wasn't designed for secrecy, was it? Imagine you're sending a postcard. Anyone along its route can take a peek at the message. When we're talking about your financial info, legal documents, or even proprietary business data, that's just asking for trouble. My aim is to give you the knowledge and tools you need to make your email communications much more secure. We'll go through all the details, check out the tech,…  ( 8 min )

This past week, I started the SheFi course— a program designed to help women dive deeper into Web3 and decentralized finance. One of the first topics it covered was Ethereum: what it is, why it matters, and how it fits into the broader decentralized ecosystem. To build on what I learned there, I read two excellent overviews: “A Beginner’s Guide to Ethereum” from Coinbase and “Getting Up to Speed on Ethereum” by Matt. Both helped frame Ethereum not just as a cryptocurrency, but as a foundational platform for Web3 applications. Here’s what stood out and why Ethereum remains vital in a rapidly evolving cryptocurrency ecosystem. Ethereum is a decentralized computing platform. Think of it like a global computer that anyone can access, but no single person or organization controls it. This is po…  ( 7 min )

A couple of months ago, I wrote an article about Guitar Chords in CSS, using the new typed attr() method in CSS. I didn't plan to write a follow-up, but then I saw these beautiful posters and wanted to do something similar. It turned out to be way more complicated than guitar chords! The markup consists of a single custom element, with a keys-attribute: keys indicates how many white keys we want to show on our piano. For now, that's all we need; all the heavy lifting is done in CSS. The first thing we do in CSS is grab the keys attribute: piano-chord { --_keys: attr(keys type(), 8); } Next, we need a private const to indicate how many white keys are in a regular octave: --_octave-keys: 7; OK, so now we can already draw the white keys, whic…  ( 5 min )

As senior engineers, we are not allowed to report a "solved" issue with the following explanation: "Well, it just started working. I don't know how, but it's fixed for now." Why? Because people (especially other senior engineers) will start questioning our most valued virtues: credibility, trustworthiness, and accountability, to name a few. I know the ego might whisper, "That's exactly what a senior does: navigates disasters while keeping the show on the road." Well, that's not quite accurate. Let me tell you why. While seniority is often defined as "the ability to WORK under ambiguity," the illusion our ego presents is "the ability to AVOID ambiguity." Notice the difference: "work under" versus "avoid." A junior engineer is hired to "avoid" ambiguity. Once they get stuck, they are suppose…  ( 4 min )

Your API got hammered by bots? Server bills through the roof? Been there! Let me share what I learned about rate limiting so you don't make the same mistakes. Rate limiting = API bouncer. Controls requests per time window. Essential for performance, cost control, and preventing abuse. Easy to implement with express-rate-limit. Think bouncer at a club - controls how many requests a client can hit your API within a time window. Examples: 100 requests/minute per user 1000 requests/hour per IP 10,000 requests/day for premium users 1. Prevent API Abuse 2. Fair Usage 3. Cost Control 4. Better Performance Node.js + Express (easiest way): const rateLimit = require('express-rate-limit'); const limiter = rateLimit({ windowMs: 15 * 60 * 1000, // 15 minutes max: 100, // limit each IP to 100 req…  ( 5 min )

Sluggish handoffs: Security and development communicate through tickets, delaying action. Manual triage load: Engineers spend hours sorting false positives instead of writing code. Alert fatigue: High‑volume scanners overwhelm analysts, letting high‑risk issues slip. Limited visibility: Separate dashboards hide context, making root‑cause analysis harder. ChatOps brings bots into workplace chat tools such as Slack or Teams. These bots link directly to scanners, CI pipelines, and incident‑response scripts, turning chat into a command console. Core elements include: Immediate notification – Findings appear in a channel the moment scanners detect them, tagged with severity and suggested fixes.

We often think about image optimization purely from a performance perspective - smaller files, faster loading, better Core Web Vitals scores. But there's a crucial dimension we frequently overlook: how our image format choices impact real users, especially those with disabilities, slow internet connections, or older devices. Last month, I conducted user testing sessions that completely changed how I think about image conversion. Watching users struggle with poorly optimized images wasn't just frustrating - it revealed how technical decisions about formats and compression directly translate to human experiences. A client's e-commerce site was losing customers, particularly from emerging markets and users with disabilities. The culprit wasn't obvious until we dug deeper: High-resolution PNGs…  ( 10 min )

Press % in normal mode to select the entire buffer. This selects all visible lines, preparing them for piping. Hit | to enter pipe mode. This allows you to send the selected text to any shell command, similar to piping in a traditional shell. This feature is incredibly useful for ad-hoc transfor…  ( 4 min )

Go isn’t flashy. It’s not packed with features. And that’s exactly why it wins in production. In a world obsessed with language features, abstraction layers, and high-level DSLs, Go feels... boring. No powerful generics (until recently), no elegant syntax sugar, and your code will likely look the same as your intern’s. But that’s not a flaw. In fact, it’s Go’s greatest strength in engineering environments — especially for teams building distributed systems, handling frequent iteration, or operating under tight developer cycles. Let’s break it down. Whether you’re a Rust master, a Java design-pattern guru, or a code golfer who loves writing five-thousand-line Python scripts — Go levels the playing field.

1. Introduction: Trust without Referents 2. What the Paper Demonstrates What these patterns reveal is that syntax itself has become a financial instrument. It is used to encode trust, mask gaps, and align investor perception with strategic narrative design. 3. Why This Matters Now 4. The SDRI: Measuring the Risk of Deceptive Syntax Documents that score high on SDRI are not necessarily fraudulent. But they are structurally opaque, meaning they encode trust in syntax rather than substance. 5. Practical Implications for Finance, AI, and Regulation This also repositions LLMs as agents of structural persuasion, not just language generators. When trained on disclosure corpora, they not only reproduce formats. They simulate legitimacy itself. 6. Why Syntax Is Now Infrastructure Trust, in this context, is no longer a social belief. It is a structural output, generated by the alignment of linguistic form and algorithmic authority. **7. Where to Read and Share Agustin V.

Do you remember when humans used to write step-by-step tutorials? Let’s bring that back. Today you’ll learn how to configure high availability for the OpenTelemetry Collector so you don’t lose telemetry during node failures, rolling upgrades, or traffic spikes. The guide covers both Docker and Kubernetes samples with hands-on demos of configs. But first, let’s lay some groundwork. You want to ensure telemetry collection and processing works even if individual Collector instances fail. It’s outlined in three main points: Avoid data loss when exporting to a dead observability backend. Ensure telemetry continuity during rolling updates or infrastructure failures. Enable horizontal scalability for load-balancing traces, logs, and metrics. To enable high availability it’s recommended th…  ( 19 min )

If you’ve ever tried to extract data from a blockchain, you know it’s not exactly plug-and-play. You’re dealing with distributed infrastructure, frequent reorgs, and often incomplete APIs. The data’s all there — somewhere — but getting it out, structured, and production-ready is a project of its own. In our full deep dive, we explore the whole landscape. This is a shorter version — a technical summary of the different approaches and tools we’ve seen work when you need blockchain data at scale. Every blockchain indexing setup starts with the node. It exposes an RPC interface that lets you query raw data from the chain. On Ethereum, the most straightforward way to get started is with eth_getLogs. Logs are emitted by smart contracts to provide information for off-chain consumers — they exist …  ( 13 min )

I have been using hledger as my primary personal accounting software for years. I love that I can manage my ledger in plaintext and even use Git to version control and backup. But when it comes to generating reports, it often takes me time to figure out all the commands I need. Also, having a way to archive previous data is important. I used to write a shell script with all the report commands, and add a lot of echo statements to generate a markdown report. However, this approach is hard to read and makes the template difficult to maintain. That's why I made mdsh, a markdown template engine written in Go, which allows you to execute shell scripts within Markdown. It allows you to use Go's template syntax in markdown, and puts the execution results in the generated output. You can install i…  ( 6 min )

What is a Promise? A promise is an object that represents the eventual completion (or failure) of an asynchronous operation and its resulting value. placeholder for a value that will arrive in the future. A promise can be in one of three states: Pending - initial state, not fulfilled or rejected. Fulfilled - operation completed successfully. Rejected - operation failed. Consuming a Promise .then() is called when the promise is fulfilled. .catch() is called when the promise is rejected. .finally() runs regardless of success or failure. fetch Why Use Promise? Before promises, we used callbacks, which could lead to "callback hell", deeply nested functions that are hard to read and maintain. Promises solve that by: Making code more readable Making error handling easier Chaining operations Promises in JavaScript - a very important topic for writing clean, modern asynchronous code.  ( 3 min )

As cloud engineers, architects, or consultants, we often hop between cloud platforms—designing, deploying, and managing infrastructure. One thing remains central across these platforms: Identity and Access Management (IAM). Control who can do what, where, and under what conditions. But how each cloud enforces this principle is where the real difference lies. The Similarities Across AWS and GCP, IAM shares these key traits: Access Control: Both platforms allow you to define who can access specific resources and what actions they can perform. Least Privilege Principle: They enforce minimal access by default, encouraging the principle of least privilege. Policy-Based Authorization: Both use a policy model (GCP uses role bindings; AWS uses policies attached to identities). Resource-Level Gra…  ( 4 min )

eMMC (embedded MultiMediaCard) is widely used in embedded systems and single board computers (SBCs) like the RK3568 System on Module for storing OS images and application data. But how do you know when your eMMC is failing — before your device stops working entirely? In this post, I’ll share 5 real-world signs that your eMMC is damaged — based on over a decade of debugging embedded systems in production environments. 🛠️ 1. File System Suddenly Goes Read-Only Debug Tip: Check dmesg | grep mmcblk for I/O error messages or block-level failures. ⚠️ 2. Random Boot Failures or Kernel Panics Use Case: We've seen this pattern frequently on RK3566/RK3568 SOMs in field-deployed equipment. 🔍 3. Unexpected Application Crashes or Data Corruption What to look for: File-not-found errors, corrupted databases, or inconsistent app state on reboot. 📈 4. I/O Performance Degradation Pro Tip: Regularly benchmark your I/O performance in production builds to spot degradation early. 📉 5. SMART or Health Status Tools Report Failures Learn more in our RK3568 SBC documentation. ✅ Bonus: How to Prevent eMMC Failures Avoid excessive logging to disk (use tmpfs for logs if possible) Choose industrial-grade eMMC chips Monitor device health regularly Schedule periodic backups or snapshotting where applicable 💡 Closing Thoughts If you're building products based on Rockchip platforms like RK3568 or RK3566, make sure to choose SOMs with reliable eMMC and long-term lifecycle support. 👉 Check out our RK3568 SOM product here — with industrial-grade eMMC and extensive software support.  ( 4 min )

In today’s digital world, UI UX design plays a critical role in determining the success of websites, mobile apps, and software products. A seamless user experience (UX) combined with an intuitive user interface (UI) can significantly improve user satisfaction, engagement, and conversion rates. Let’s explore why UI UX design matters, its core principles, and how it benefits businesses. What is UI UX Design? UI UX design refers to two interrelated disciplines: User Interface (UI): Focuses on the look, feel, and interactivity of a digital product. It includes visual elements like buttons, icons, typography, color schemes, and layout. User Experience (UX): Involves the overall experience users have when interacting with a product. It emphasizes usability, functionality, and user satisfaction. …  ( 4 min )

Most of my friends knew what they wanted to be in high school. I didn’t. Well, I thought I did. I wanted to become a petrochemical engineer because they were earning a lot of money, or so I thought. The problem was, I didn’t like chemistry. Failed it twice. I still thought this was my path because, you know, the money. That was my plan for a while, until a tutor came to the tutorial center where I was preparing for college one day and said, “Most students study courses they don’t like. They do it for money, or because their parents want them to, or because companies pay well. Go home and think about what you actually love doing.” I went home and thought hard. Chemistry was out—obviously not happening. But I’d always loved web applications—in fact, tech as a whole. After school, I’d hang ou…  ( 6 min )

On 30 November 2022, ChatGPT, the product of OPENAI, saw the light of day, and it was my first “really conscious” technology drift of my life. I experienced both the rise of social networks and the spread of fast internet connections, but at the time, I was too young to have a before-and-after comparison. This time, it was different. I was completing my Master's degree, and my last few years were quite similar (learning, studying, trying, doing other stuff-ing, completing exams), so I have a clear comparison of tasks influenced by this tool. To be honest, at the beginning it was a great tool for writing, summarizing, and generating Q&A for my mock exams. It was not a good programmer, though. But it solved a lot of boring stuff about my student life. I started to use it. Recognizing this ch…  ( 19 min )

In Salesforce development today, the conversation is dominated by Lightning Web Components (LWC). It’s modern, performant, and built for the future of the platform. With all this buzz, it’s easy to wonder: does that mean older frameworks like Visualforce are obsolete? The answer is a definitive no. While it may be the senior framework, Visualforce remains a powerful and highly relevant tool for specific use cases. Think of it as a specialized instrument in a developer’s toolbox—just because a new multi-tool exists doesn’t mean you throw away the perfect wrench for a specific job. Why Visualforce Still Has a Place The key difference lies in the rendering model. Visualforce is a server-side framework, meaning all the heavy lifting—like data processing and page compilation—happens securely on…  ( 5 min )

This is a submission for Frontend Challenge: Office Edition sponsored by Axero, Holistic Webdev: Office Space As an employee, I've often wondered if there was a single website where I could view everything at a glance to start the day. Despite the fact that there are planning, product development tools, and dashboards, all of the information is spread across multiple websites. I was able to design a simple prototype of a company landing page that summarizes all data for a quick glance throughout the day. Please access the live URL and view the details. Live URL Github Repo As I previously stated, my intention was to put all necessary data on the home page. It was difficult to design such a page. After looking for inspiration and incorporating UI elements from existing established solutions, I was able to create a minimal solution, which still requires a lot of work. This design is heavily reliant on Shadcn UI and blocks produced from it via various websites. Also the color theme is adapted from Catppuccin color palette. The UI is currently immature, but the main goal is to consolidate all critical information on the home page. If you believe there is something missing, please leave a comment.

“All models are wrong, but some are useful.” George E. P. Box In the data world, this quote reminds us that while no transformation or model perfectly captures reality, some techniques make our data more useful. One such technique is log transformation, a simple yet powerful tool for making messy data more model-friendly and interpretable. Log transformation is a mathematical operation that converts a variable by taking its logarithm — often natural log (ln) or base-10 (log10). It’s primarily used to: Reduce skewness Handle large outliers Stabilize variance Convert exponential relationships into linear ones If you have a variable x, then its log-transformed version is log(x). But be cautious: only positive values can be log-transformed. Many real-world variables like income, population, o…  ( 4 min )

How can Developers 💪help💪 or 💥hurt💥 the Daily Scrum? The goal of the Daily Scrum is to inspect progress toward the Sprint Goal and adapt the Sprint Backlog as necessary, adjusting the upcoming planned work. I like to think of it as the Developers agreeing on how to work together towards the Sprint Goal for the next 24 hours. Hurts: 💥 Play (bad) Project Manager, taking progress reports, assigning work and talking in ticket numbers. 💥 Holding work hostage, being vague about progress, covering up potential issues and removing the possibility for the team to help. 💥 Waste time by showing up late and unprepared or going super in-depth Helps: 💪 Run It!

We all love what massive Transformers can do—stunning few-shot learning, tricky reasoning, code completion, etc. But let’s be real: scaling up to billions of parameters means you need serious hardware and cash, whether you’re training or deploying. Parameter Sharing: Reuse the same weights across layers (think: Universal Transformers, recurrent models). Saves memory, but doesn’t solve compute waste.

Often considered secondary to the benefit of an application that executes quickly (and without error), the chosen architecture nevertheless has a crucial place in the project, to ensure the sustainability of current and future developments...

JavaScript includes several operators that look similar but do very different things.

Here’s a quick guide to each — what they do, how they differ, and when to use them. ? :) What it does: The ternary operator is a one-line shorthand for an if...else statement, letting you pick one of two values based on a condition. Syntax: condition ? valueIfTrue : valueIfFalse Example: const age = 20; const message = age >= 18 ? "Adult" : "Minor"; // "Adult" // Equivalent to: // let message; // if (age >= 18) { // message = "Adult"; // } else { // message = "Minor"; // } ?.)

Unsupervised learning falls under machine learning and it deals with unlabeled data. Without any human supervision unsupervised learning tries to find patterns, structures, relationships in the input data. Imagine having a large dtaset of customer transactions without having any predefined customer sections. But you start grouping the customers based on their purchasing habits. Unsupervised learning works by analyzing unlabeled data to identify patterns and relationships. The data is not labeled with any predefined categories or outcomes therefore the algorithm must find these patterns and relationships on its own. There are three key types of unsupervised learning.

Software development is how we make apps, games, and computer programs. It may sound hard, but with the right tools, it becomes easier. These tools help developers write, test, and fix code. Just like a carpenter needs a hammer, software developers need their own set of tools. Let’s learn what they use! A code editor is like a notebook where developers write code. It shows the code in a clean, easy-to-read way. It also highlights parts of the code using different colors. This helps find mistakes faster. Some popular code editors are Visual Studio Code, Sublime Text, and Atom. They are simple and fun to use. Computers don’t understand human words. They only understand machine language. A compiler turns the code written by a developer into something a computer understands. Think of it like G…  ( 7 min )

According to GitHub, more than 40% of developers now use Copilot. But are we trusting AI too much, too fast? A new trend called vibe coding is gaining traction. While it can accelerate development, it also introduces silent risks — especially when AI-generated code is deployed in production without thorough review. As AI-assisted development tools become mainstream, developers are increasingly relying on tools like GitHub Copilot or ChatGPT to write code with minimal understanding of the underlying logic. This trend, commonly referred to as vibe coding, poses hidden risks, especially in production-grade systems. In this article, I explore what vibe coding is, its dangers, and how developers can avoid its pitfalls. Vibe coding is an emerging development method where users interact with larg…  ( 5 min )

You’ve got a massive feature idea. It's exciting. It's visionary. But it's also… overwhelming. “Where do I start?” “How do I plan this with my team?” “Why does everything feel stuck during sprints?” If you've ever faced this, you're not alone. The truth is: most teams fail not because of bad ideas — but because of poor breakdowns. Let’s fix that. Here’s a step-by-step breakdown of how to turn chaotic epics into crystal-clear user stories that are easy to estimate, assign, and deliver — without burnout or confusion. Really? An epic is just a large feature or requirement that’s too big to be completed in a single sprint. For example: “Build user authentication system” — sounds reasonable, but that’s actually an epic.

I’m excited to share an open-source project I’ve been working on called Timestone, a small but handy Java library for abstracting time sources and writing deterministic, testable time-based logic. If you’ve written code that deals with: session expiration retries with timeouts scheduled jobs or caches with TTLs then you know how painful it can be to test anything involving the passage of time. For instance, Thread.sleep(1000); assertTrue(Duration.between(start, Instant.now()).toMillis() > 1000); This is flaky, slow, and impossible to speed up in unit tests. While building time-based systems, I noticed that many open-source projects, Apache Kafka and Apache Flink for example, rolled their own fake clocks and manual timers to simulate time. I kept seeing duplicated patterns across internal …  ( 4 min )

Demystifying Graph RAG: Transformative Approaches to Agent-Centric Systems Introduction Hello everyone, I'm excited to discuss a topic that has recently gained traction in the tech industry: Graph RAG (Retrieval-Augmented Generation). I recently began writing a book on the subject, and I can't wait to share some insights from my research and experiences. Graph RAG connects the dots between graph databases and natural language models (NLMs), allowing for smarter, more efficient ways to handle data retrieval and agent memory systems. Graph RAG is a novel approach that combines the capabilities of graph databases with retrieval-augmented generation techniques. This synergy helps in creating intelligent agent systems that can efficiently search, filter, and retrieve relevant infor…  ( 5 min )

Every developer has that one script. The one you tweak, expand, and refactor until it barely resembles the original. For us, that script was the seed for Object Sense (OSE). What started as a custom VimL tool to solve our own workflow problems has, as of last month, evolved into OSE V3: a modern, general-purpose language we're now opening up to the world. This is its story, and why we think it matters in the age of AI. The Problem That Sparked a Language Back in 2022, our team at Codigger was building complex distributed systems. We were constantly fighting friction between different tech stacks: our core logic was in Java, our data scripts in Python, our automation in Shell, and our internal tooling still had remnants of VimL.

Modern business processes demand flexibility, configurability, and reusability in automating decisions, validations, and actions across domains like entitlement assignment, pricing, fulfillment, and compliance. However, traditional hard-coded logic in Salesforce (Apex triggers, workflows, etc.) is often difficult to maintain and adapt as business requirements evolve. Key Challenges Lack of Flexibility: Hard-coded rules require code changes for modifications. Redundancy: Similar logic is duplicated across objects and processes. Limited Reusability: Conditions and actions aren’t easily shared or reused. Business User Empowerment: Non-technical users can’t easily manage or update business rules. Design Approach To address these challenges, we propose a generic, extensible rules engine built o…  ( 5 min )

In a world flooded with productivity tools, one thing remains stubbornly outdated: how we track time. For years, teams have logged hours, filled timesheets, and measured productivity with the blunt metric of "time spent."

If you're doing any Object-Oriented programming, chances are your code is bloated. If you're working on an enterprise application, even more bloated. One recurring, boring, time-consuming and error-prone pattern that occurs across the whole codebase and that's so hard to remove that most OOP programmers just get on with to get their paycheck is the Adapter Pattern, otherwise known as just "glue code". Large numbers of object instances laying in your codebase, each with a different API and some methods named after some squeezed-together English words to give a hint at what they do.

Hey community! 👋 how to optimize like a pro with Memoization, Suspense, and more. 🚀 ✅ 1. React.memo – Stop Unnecessary Re-Renders By default, React re-renders a component when its parent updates—even if props didn’t change. const Button = React.memo(({ label }) => { console.log('Rendered!'); return {label}; }); ✔ Only re-renders when label changes. ✅ 2. useCallback – Stable Functions Across Renders Passing inline functions as props? It causes re-renders. const handleClick = useCallback(() => { console.log('Clicked!'); }, []); ✔ Great for event handlers in child components. ✅ 3. useMemo – Cache Expensive Computations If you compute heavy values on every render, use useMemo to cache the result. const sortedData = useMemo(() => { return data.sort((a, b) => a.value - b.value); }, [data]); ✔ Only recalculates when data changes. ✅ 4. Suspense – Smarter Loading States Instead of conditional rendering everywhere, use React Suspense with React.lazy. const Profile = React.lazy(() => import('./Profile')); ✔ Handles lazy-loaded components gracefully. ✅ 5. Code Splitting – Load Only What You Need Big bundle? Split it into chunks using dynamic imports or tools like Webpack. const Settings = React.lazy(() => import('./Settings')); ✔ Reduces initial load time. ✅ Bonus: Profiler & DevTools Use React Profiler to identify slow components. ✅ Chrome DevTools → Components tab → Profiler 💬 What’s your go-to React optimization trick?

If you've been reading about Cross-Origin Resource Sharing, or CORS in short, there is a good chance that you've come across this term: Preflight Request. It's an extra HTTP request that the browser makes before the actual, cross-origin request to make sure it's safe to send. It's basically an HTTP OPTIONS request that is automatically sent by browsers before certain cross-origin requests. It checks with the web server, and only if the server responds with the right CORS permissions does the browser proceed with the real request, otherwise the browser blocks it. This makes CORS secure: a browser checks both origin and intent before sending your actual data. Let’s break it down with a real example: OPTIONS /resource HTTP/1.1 Host: api.example.com Origin: https://app.example.com Access-Contr…  ( 5 min )

Excited to share my latest open-source project: the AI Agent Tester! As AI models become more integrated into our applications, how do we ensure their responses are consistent and reliable? Manually testing prompts is slow and doesn't scale. That's why I created this tool. The AI Agent Tester automates the validation process. It reads prompts from a simple CSV file, sends them to an AI (like OpenAI's GPT), and checks the responses for expected keywords. Here’s what makes it effective: Intelligent Validation: It uses "stemming" with NLTK to recognize word variations (e.g., 'fly', 'flying', 'flew'), making validation more robust. Detailed Reports: It generates a JSON report with the status (Success/Fail) for each prompt, along with the AI's full response. Easy to Use: Built with Python and requires minimal setup. It even has automatic proxy support for corporate environments. This project is for any developer or QA engineer working with Large Language Models who wants to add a layer of automated testing to their workflow. It's open-source, and I would love to get your feedback or contributions! Check out the project on GitHub: https://github.com/lfrichter/ai-agent-test  ( 3 min )

GitHub Homepage During my junior year studies, WebSocket technology has always been my most interested real-time communication solution. Compared to traditional HTTP polling, WebSocket provides true bidirectional real-time communication capabilities. Recently, I deeply studied a Rust-based web framework whose WebSocket server-side processing implementation gave me a completely new understanding of modern real-time communication technology. In my previous projects, I used Node.js Socket.io to implement WebSocket functionality. While powerful, its complex configuration and high resource consumption left a deep impression on me. // Traditional Node.js WebSocket implementation const io = require('socket.io')(server); const clients = new Map(); io.on('connection', (socket) => { console.log('…  ( 8 min )

GitHub Homepage: https://github.com/eastspire/hyperlane My journey into robust error handling began during a production incident where a single unhandled exception brought down our entire web service. The cascade failure taught me that error handling isn't just about preventing crashes—it's about building resilient systems that gracefully degrade under stress while maintaining service availability. This experience led me to explore error handling strategies that could maintain both performance and reliability. The critical insight came when I realized that traditional error handling approaches often create performance bottlenecks through excessive exception throwing, complex stack unwinding, and resource cleanup overhead.

You’ve got your AI model behaving well. You’ve cleaned your data. You’ve built guardrails to handle prompt injection. But here’s the catch — none of that matters if your API is wide open or your frontend leaks keys. In this post, we’re tackling a layer that often gets ignored: the infrastructure between the user and the model — specifically, your API layer and frontend interface. If you’re using FastAPI, Gradio, or any framework for your AI apps, this is for you. AI APIs are a goldmine for attackers: They expose high-value endpoints (e.g., GPT-4, Gemini, Claude) They often have low/no auth in MVPs and prototypes They can leak sensitive info in logs or responses They are expensive to run, abusing which means real money lost Your model might be smart, but if anyone can POST to your /generate…  ( 6 min )

GitHub Homepage: https://github.com/eastspire/hyperlane My deep dive into context management began during a performance optimization project where I discovered that inefficient request context handling was creating memory leaks and performance bottlenecks. Traditional web frameworks often treat context as an afterthought, leading to resource waste and complex state management. This experience led me to explore how sophisticated context management can dramatically improve both performance and developer experience. The pivotal insight came when I realized that request context isn't just about passing data between functions—it's about creating an efficient, type-safe mechanism for managing the entire request lifecycle.

Author: Steve Tuohy - Director of Product Marketing Discover how Criteo scaled to 290M queries-per-second, swapped Couchbase + Memcached for Aerospike, cut servers by 78%, and kept sub-ms latency. Criteo serves more than 700 million users daily with personalized ads, processing billions of events in milliseconds. At its peak, Criteo’s infrastructure handles 290 million key-value queries per second (QPS). Until recently, this real-time engine ran on a complex stack of Couchbase and Memcached, propped up by custom C clients and costly operational overhead. Performance during rebalancing was fragile, cache warming required manual traffic shaping, and RAM costs were high. But when Criteo rebuilt its stack using Aerospike’s patented Hybrid Memory Architecture (HMA), the company consolidated two…  ( 6 min )

GitHub Homepage As a junior computer science student, I gradually recognized the importance of asynchronous programming during my web development learning process. Traditional synchronous programming models often cause thread blocking when handling IO-intensive tasks, while asynchronous programming allows programs to continue processing other tasks while waiting for IO operations. Recently, I deeply studied a Rust-based web framework whose asynchronous programming implementation gave me a completely new understanding of this technology. In my previous projects, I used traditional synchronous programming models. While this model has clear logic, it encounters serious performance bottlenecks when handling large numbers of concurrent requests. // Traditional synchronous programming example @R…  ( 8 min )

In the previous post, we established that simplicity is about reasoning—the ability to clearly understand what a system does, how it works, and why it behaves in a particular way. To understand what impedes that reasoning, this post takes a step back to analyze the fundamental nature of the systems we build. We will borrow insights from the field of cybernetics to dissect how modern software works, on a search to diagnose what precisely makes it complex. In computer science, a "Turing complete" system is capable of performing any computation a theoretical Turing machine can. All modern programming languages are Turing complete, providing the fundamental power to build incredibly diverse applications.

In software architecture, Push and Pull models define how data flows between a producer (like a server) and a consumer (like a client). While both are valid, choosing the right one can significantly impact user experience, system performance, and scalability. In a Push model, the server initiates the communication. It sends (or "pushes") data to the client whenever something new happens. The client doesn’t have to ask—it just gets notified. Low latency Real-time experience Efficient for frequent updates More complex to implement Harder to scale with many clients 🧠 Examples: WebSockets, Firebase Realtime Database, Server-Sent Events In a Pull model, the client initiates the communication. It regularly or occasionally requests data from the server, asking, “Do you have anything new?” Simple…  ( 4 min )

If you’ve just installed Python on Windows and when trying to run python from the Command Prompt you see this message: "Python was not found; run without arguments to install from the Microsoft Store, or disable this shortcut from Settings > Apps > Advanced app settings > App execution aliases." Don’t worry This is a common problem caused by Windows redirecting your Python commands to the Microsoft Store. In this post, I’ll walk you through the exact steps to fix it, so you can start coding right away. What Causes This Issue? Windows 10 and 11 have a feature called App Execution Aliases that adds shortcuts for certain apps, including Python. If Python isn’t properly installed or the PATH isn’t set, Windows tries to redirect your command to the Store to download Python. This causes confusion because even if you installed Python manually, typing python will still bring up this message. Step-by-Step Fix: Disable Python App Execution Aliases Step 1: Open Windows Settings Press Win + I on your keyboard This opens the Settings window Step 2: Navigate to App Execution Aliases In Settings, click on Apps Then click on Advanced app settings (or search for “App execution aliases” in the Settings search bar) Scroll through the list until you find: python.exe python3.exe Step 3: Disable the Aliases Step 4: Verify the Fix Bonus Tips If you don’t see Python in your PATH, you can manually add it by editing your environment variables. Use python -m pip instead of just pip to ensure you’re using the correct pip for your Python version. Summary Disabling the Windows App Execution Aliases for Python is a quick and effective fix for the “Python was not found” error. Once disabled, Windows stops redirecting your commands to the Microsoft Store, and you can run Python smoothly from the terminal.  ( 4 min )

Your University Website Will Never Go Down Again — Beginner Friendly System Design Let’s create a very simple and absolute beginner-friendly system design for our university website. On usual days when no results are declared, no announcements are made, and no admit cards are released, the traffic on the website is very normal. In an ideal case, let's start from a very simple design — no load balancer, no auto-scaling, none of those typical complex components. Server: This can be any highly configured machine that is up and running 24/7. Technically, your personal laptop can also act as a server — but obviously, no one wants that. DNS (Domain Name System): It’s a global directory that maps domain names to IP addresses. You pay for that public IP. At the time of result declaration or admit card release, traffic increases drastically. The same server configuration cannot handle the sudden surge in requests. The result? The application faces downtime or crashes. So, what can we do? We can increase the configuration of the server from: 4 CPUs → 8 CPUs 64 GB RAM → 128 GB RAM This is called Vertical Scaling, which means increasing the power of the existing machine. We cannot increase the configuration of a running server. First, we need to stop the server, upgrade it, and then start it again — which causes downtime. It’s not recommended for high-availability applications. So, what else can we do? We can use Horizontal Scaling, where we replicate the resources — basically, we add new servers instead of upgrading the existing one. A new IP will be assigned to each new server. But, all requests will still go to the original server unless we have a way to distribute traffic. Any idea how to solve that? Well, this is what I’ll discuss in the next design! 🚀 Stay tuned for the next part where we’ll talk about load balancers, traffic distribution, and more smart strategies to handle peak-time traffic without breaking the system! ✍️ Author: Omkar Sharma 📬 Feel free to connect on LinkedIn or explore more on GitHub  ( 4 min )

This may sound like the worst idea ever. But I think there is no better time than now. Despite new frameworks popping every week, devs' burnout keeps escalating; the ecosystem is bursting at the seams, and Vercel monopoly gives billing nightmares. For my solution to succeed, it just needs to be: Composable components, shared and local state, reactivity. Natural SSR (not by running front-end code on the server), fast loading, functional href, real FormData, and execution transparency (that was lost). Static endpoints only for serving files and pages.

Chat interfaces have surged in popularity, becoming a common entry point to intelligent systems. But while text excels at expressiveness and simplicity, it's often limiting for structured interactions. Booking a meeting, selecting options, or reviewing results all demand more than just words. The immediate solution that comes to mind is to render traditional user interfaces (components) inside the agentic system, but what does that look like in practice? What are the viable strategies for embedding UI into chat-driven workflows? And even better: should you be embedding UI at all? If so, will these new approaches eventually replace traditional interfaces, or simply augment them? In this article, we are going to look at the three emerging strategies for returning UI from agents: First-party …  ( 8 min )

Building a Custom Video Editing Backend with LLMs and Declarative Composition I’ve been exploring how large language models (LLMs) can be used to automate video editing. At first, I thought the process would be relatively straightforward: describe the edit in natural language, have the LLM translate that into actions, and render the result. Initially, I tried using FFmpeg with LLMs to handle basic video operations like trimming and transitions. But it didn’t work well. The generated code was brittle, and FFmpeg’s syntax is not easy for LLMs to handle reliably, even with refined prompts. To solve this, I created a custom markup system called Swimlane Markup Language (SWML) — a JSON-style declarative format that describes the video structure. It allows LLMs to express compositions in a for…  ( 4 min )

It was one of those moments for me when a simple task gets you into a 4-hour rabbit hole that teaches you more than months of reading. I was just trying to SSH into my own machine (yep, localhost), and suddenly, ofc nothing worked right. When a Simple Task Goes Wrong   # From inside the container, tunnel to host services ssh -L 5432:localhost:5432 user@host.docker.internal Before involving the container, I wanted to test the connection on my host machine first. A simple SSH to myself should happen quickly, right? ssh shivam@localhost It worked, but it felt slow. Really slow. An instant connection took several seconds. If my containers were going to use this for database connections, that lag would hurt performance. Something was off, and I needed to find out why. **Step 1: Checking the B…  ( 6 min )

The world of generative AI is expanding at an incredible pace. Developers now have access to a powerful array of Large Language Models (LLMs) from providers like OpenAI, Google (Gemini), Anthropic (Claude), and a vast collection available through services like AWS Bedrock and Hugging Face. While this choice is empowering, it introduces a significant challenge for engineering teams: each model comes with its own unique API, SDK, and authentication mechanism. Managing this complexity can lead to a fragmented codebase, vendor lock-in, and operational headaches. What if you could interact with all of these models through a single, consistent interface? Enter LiteLLM, the open-source library designed to be the Swiss Army knife for GenAI deployment. It provides a universal translation layer, all…  ( 5 min )

Following one of C++ course I found one interesting example how to correctly use combination std::cin together with std::getline(). What do you think the output will be ? To avoid this strange behaviour always use std::cin.get() before std::cin and std::getline() like on the code snippet below: Now you will get correct output. Be careful and happy coding!  ( 3 min )

Of course. The screenshot shows a cascade of compilation errors all originating from a build path or dependency issue. The IDE can't find your own custom classes like CifnLayoutRecord and LoggingUtil. Here is the complete, corrected code for DemographicSubscriberService.java. The fixes include: Adding Correct Imports: Placed all the necessary import statements at the top, which will resolve the "Cannot resolve symbol" errors. Handling Nulls: Added a null check after attempting to parse the record, as hinted by the "Value 'cifnLayoutRecord' is always 'null'" warning. Handling Exceptions: Wrapped the calls to maskJson in a try-catch block to handle the JsonProcessingException. Correcting Method Calls: Ensured the method calls to the transformers and Kafka service are correct now that the…  ( 4 min )

Part 3: Executing Commands in a Custom Shell (C Programming) In this final part of my custom shell project, we’ll explore how to execute user commands after they’ve been parsed. At this point, the user input has been successfully split into arguments — now it’s time to take action! 💥 execute_command Function The core function here is: void execute_command(char **args, int argc, Command *command, int command_count) ✅ Matches user input with a predefined command Let’s break it down 👇 for (int i = 0; i < command_count; i++) { if (strcmp(args[0], command[i].name) == 0) { command[i].action(args, argc); return; } } printf("Unknown commnad: %s\n", args[0]); Command Matching: The shell loops through an array of Command structs and compares the input with registe…  ( 5 min )

FSCSS @random Method The @random method in FSCSS (Figured Shorthand Cascading Style Sheet) provides a robust mechanism for applying randomized values to CSS properties, enabling dynamic and varied styling that refreshes on each page load. By selecting a single value from a provided array (e.g., colors, numbers, or units) at render time, @random facilitates the creation of visually diverse UI elements without requiring JavaScript or manual intervention. When used in conjunction with the @arr FSCSS array utility, @random streamlines the process of defining and reusing arrays of values, enhancing code efficiency and maintainability. This combination allows developers to manage randomized styles with precision and minimal effort. Below is an example of FSCSS code leveraging @random and @arr:…  ( 4 min )
